I have tried to install Math Convnet toolbox. I am follwing the instructions in http://www.vlfeat.org/matconvnet/quick/. when i use the comment " run matlab/vl_compilenn", (third comment) i am getting the following error.
SWITCH expression must be a scalar or string constant.
Error in vl_compilenn (line 181) switch opts.imageLibrary
Error in run (line 64) evalin('caller', [script ';']);
Kindly help me. Thanks in advance.

I don't know. Your best approach is to contact the author of that toolbox.

That code is only for 64 bit architectures; I suspect you are trying to run it with 32 bit MATLAB.

You would need R2015b or earlier to run the 32 bit version.
However, it appear to me that the current versions of matconvnet should be suitable for 64 bit versions.
