Subspaces Angle (G Dataflow)

A real vector.

This input accepts a 1D array of double-precision, floating-point numbers or a 2D array of double-precision, floating-point numbers. If this input is a 1D array of double-precision, floating-point numbers, you must wire a 1D array of double-precision, floating point numbers to vector b. This input changes to matrix A when the data type is a 2D array of double-precision, floating-point numbers.

Default: Empty array

A real vector.

This input accepts a 1D array of double-precision, floating-point numbers or a 2D array of double-precision, floating-point numbers. This input changes to matrix B when the data type is a 2D array of double-precision, floating-point numbers.

The length of vector a or the number of rows in matrix A must equal the length of vector b or the number of rows in matrix B. Otherwise, the node returns NaN as the output angle and returns an error.

A real matrix.

This input accepts a 1D array of double-precision, floating-point numbers or a 2D array of double-precision, floating-point numbers. This input changes to vector a when the data type is a 1D array of double-precision, floating-point numbers.

A real matrix.

This input accepts a 1D array of double-precision, floating-point numbers or a 2D array of double-precision, floating-point numbers. This input changes to vector b when the data type is a 1D array of double-precision, floating-point numbers.

The length of vector a or the number of rows in matrix A must equal the length of vector b or the number of rows in matrix B. Otherwise, the node returns NaN as the output angle and returns an error.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error
