Compiled version fails when highpass is called “Error using toolboxdir. Could not locate the base directory for dsp/filterdesign’.
I have created an App in App Designer which works fine until I compile. Everything still works as expected, except the functionality that uses the ‘highpass’ function from the Signal Processing toolbox. The log file states:
"Error using toolboxdir (line 54)
Could not locate the base directory for dsp/filterdesign.
I have checked that the toolbox is installed (I even reinstalled it again) and checked the path to the toolbox exists using toolboxdir(‘signal’).
I created a small test app that recreates the problem.The test app simply creates 100 random numbers, plots them and then applies the highpass filter on the click of a button. Again, the application fails once it is compiled.
I read that the Matlab compiler should detect and automatically include any toolbox requirements. I even tried forcing this detection by adding some non-consequential calls to highpass.m . The code for the test application is below.
Can anybody suggest what I am doing wrong?
