MATLAB does not have a polar surface plot built in. You can use a normal surface plot if you convert your polar data into Cartesian with the pol2cart command. We also cover how to get rid of the… read more >>

Recently a MATLAB user asked me how to make it possible to work with an array of structures in such a way that she could filter the array of structures and then combine the remaining fields. Once… read more >>

Sometimes MATLAB throws an error, but because the error is inside of a function you can not see what caused this error. By telling the debugger to stop execution under certain conditions or right… read more >>
