Hi, I am working on a MEX file. I am using MEXCallMatlab which is very slow to call matlab inbuilt function as well as user defined function. It is not possible for me to make mex for other files since they are in large number and each of them is calling many in-built. Thanks.

mexCallMATLAB is slow. Calling built-in Matlab functions from a MEX is no good idea.

When the main time is spent for the callimng of Matlab from inside the MEX function, and you need to call a lot of Matlab functions which call other builtins again, using a MEX-file is not an efficient approach. E.g. the creation of a usual GUI is not noticably faster when it is created as MEX function, because the creation of the UI-elements needs most of the time.
Therefore a good strategy is to find the bottlenecks of your program at first and use MEX files only for "basic" calculations.
