Logarithm Base X (G Dataflow)

Version:
    Last Modified: March 15, 2017

    Computes the base X logarithm of a specified input value.

    If y is 0, the output is - . When x and y are both non-complex and x is less than or equal to 0, or y is less than 0, the output is not a number (NaN).

    y

    An input to this operation.

    This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.

    Data Type Changes on FPGA

    When you add this node to a document targeted to an FPGA, this input has a default data type that uses fewer hardware resources at compile time.

    logx(y)

    Logarithm of y to the base x.

    When x and y are complex, the following equation defines logx(y):
    log x ( y ) = ln ( y ) ln ( x )
