Calling MATLAB from the Instrument
Calling MATLAB
Note: Load MATLAB version 6.5 just as you would on any PC. Once it is loaded, open MATLAB from the desktop, then
close it again, before you attempt to open it from the instrument application. This is to update the registry.
MATLAB can be directly called from the instrument in two ways:
Using a function
F1 through Fx The number of
math traces available depends
on the software options loaded
on your scope. See
Specifications.
MATLAB returns a waveform
Using a parameter
P1 through Px MATLAB returns a parameter
In both cases, one call to MATLAB can use two separate waveforms as input, providing much
greater computing power than is available by calling MATLAB from a VBScript.
Note: If you do not place a semicolon ";" at the end of a line, MATLAB will show the calculated value in the result window,
significantly slowing down the processing rate. This feature is best kept for diagnostics.
How to Select a Waveform Function Call
The MATLAB Waveform functions are selected from the Select Math Operator menu. Please note
that once you have clicked on "MATLAB Wave" there will be a slight pause before MATLAB starts.
