Finds the line that best represents an input signal or input data set using a specific fitting method. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application The following ...

Finds the set of polynomial fit coefficients that best represents an input signal or input data set using a specific fitting method. DAQExpress does not support FPGA devices Not supported in VIs that run ...

While execution highlighting slows the execution of your code, single-stepping allows you to have more control of viewing individual actions of the program. With execution highlighting, execution slows ...

Performs limit testing on the input signal. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application signal The input signal. This input can be a waveform or an array ...

Generates a signal containing a Gaussian white noise wave. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Generating the Gaussian White Noise ...

Returns various measurements of a specific pulse in a periodic waveform or an array of periodic waveforms, such as the period, pulse duration, and duty cycle. DAQExpress does not support FPGA devices Not ...

Use a Case Structure to incorporate decision logic into your program. A Case Structure contains one or more subdiagrams, or cases, exactly one of which executes when the structure executes. Case Structures ...

Generates a signal containing a ramp pattern of samples. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Generating the Linear Ramp Pattern Let ...

Instead of creating the same code on a diagram multiple times, you can write code in a single location and use a For Loop to programmatically repeat it. For example, you might want to read a specific number ...

Creates a custom scale that scales values proportionally from a range of pre-scaled values to a range of scaled values. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application ...

Generates a signal containing a sine wave. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Algorithm for Simulating a Sine Wave If sequence Y represents a sine ...

Compares two values and returns True only if the values are equal to each other. This node can also compare an array or cluster of a data type to a scalar of the same data type and produce an array or ...

Executes its subdiagram n times. The iteration terminal provides the current loop iteration count, which ranges from 0 to n-1. DAQExpress does not support FPGA devices Supported in VIs that run in a web ...

Converts a timestamp or numeric value into a string that displays the corresponding time. This node calculates date and time string by copying time format string and replacing each of the time format codes ...

Formats data as a string and writes it to a file. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application Syntax element(s) input format string output Comments %g # ...

Generates an error report string from an error cluster. DAQExpress does not support FPGA devices Not supported in VIs that run in a web application error in Error conditions that occur before this node ...

Retrieves either the value of a single waveform attribute or the names and values of all waveform attributes. To retrieve the names and values of all attributes, select Get All Attributes in the Behavior ...

Converts the characters 0 through 9, A through F, and a through f in a string to a hexadecimal integer. DAQExpress does not support FPGA devices Supported in VIs that run in a web application The following ...

Determines whether the input value falls within a range specified by the upper and lower limits and optionally coerces the value to fall within the range. To allow the node to perform coercion, select ...

Returns the value stored in an array at a specified index. DAQExpress does not support FPGA devices Supported in VIs that run in a web application The following image illustrates this node's behavior for ...

Returns two arrays of strings listing the names of all files and folders found in the specified path. This node filters both arrays based upon pattern and filters the file names array based upon the specified ...

Searches for a pattern of characters in a string as specified by a limited set of regular expressions. If this node finds a match, it splits the input string into three substrings: the string that appears ...

Compares two values and returns the maximum and minimum values. DAQExpress does not support FPGA devices Supported in VIs that run in a web application Parameters Compare Elements Comments Compare Aggregates ...

Converts a numeric value to a string that shows the number's engineering format. Engineering format is similar to exponential format, except the exponent is a multiple of three (..., -3, 0, 3, 6, ...). ...

Computes the value of a number (x) raised to a specified power (y). If x is not complex, it must be greater than zero unless y is an integer value. Otherwise, the result is not a number (NaN). If y is ...

Reads a specified number of bytes from a byte stream file. A character refers to a code point, a numeric unit between 0 and 10FFFF16 that is subscribed meaning by the Unicode standard for encoding. You ...

Creates a complex number from two values in rectangular notation. DAQExpress does not support FPGA devices Supported in VIs that run in a web application x The x rectangular component of x + yi. This input ...

Changes the dimensions of an array according to a specified dimension size. This node reads the array data in memory from left to right, row by row and populates the reshaped array the same way. For example, ...
