I downloaded the complete toolbox named "matlab_toolboxes-master" by Gpeyre (https://github.com/gpeyre/matlab-toolboxes).

I am trying to run the matlab file \matlab-toolboxes-master\toolbox_sparsity\tests\test_mca_wavdct.m .

But I got this error again and again. Please help me as I need to complete my project by April 2019.

Thank You.

Did you try? If so did you get the same error?

I'm using Matlab 2013a. I tried other versions as well 2015a, 2017a and 2018b. But I'm getting same error and I'm stuck and I really need help.

Also, I checked the given link but I didn't find any updated code related to this particular toolbox.

I didn't try myself. I don't want to download a load of 3rd party code I don't need just to see if I see the same result as in a Matlab Answers question.
