I could not encounter any of the described issues with my installation of FlexPro (latest release 11.0.19). I created a sine signal and added a formula with
Absolute(data) to it for output. It was working just fine.
Did you try the auto-completion when typing in the first characters of
Absolute into a formula and then hit
Ctrl+Space for the list of known keywords? Is the desired function in the list?
Did you have a look into the defined templates for your project data base? (
File->Organize under “Tools”) Maybe some user defined template is overriding the definition for Absolute and Cosine function.
Here is my example code I used:
Dim n = 100
Dim dt = 0.1
Dim freq = 0.25
Dim y, t
t = dt * (n, 0, 1)
y = 1.0 * cos( 2 * PI * freq * t)
Dim _data = MySignal
Plotting MySignal and MyAbs as a 2D line plot gave the attached diagram.
