RT targets do not support the plots generated by certain MathScript RT Module functions when you do not assign the output of the function to a MathScript variable. You can use these functions on RT targets only if you assign the output of the function to a MathScript variable. For example, a = coherence(x, y) is supported on RT targets. However, coherence(x, y) is not supported, because when you call the function without assigning the output to a variable, LabVIEW generates an output plot that is not supported on RT targets.
RT targets support the following MathScript functions only when you assign the output of the function to a MathScript variable.
