Why function 'sparse' is not supported by Matlab compiler?

I want to compile some my matlab codes to generate a c++ dll, so that I can integrate it into my c++ project. But after all these thing done I run the program, some errors occurred, saying Undefined function 'sparse' corresponding to input parameters of 'int32' type.I check the source codes and found the 'sparse' was a matlab built-in function which is responsible for create a sparse matrix. so I wonder if there are other alternative for the 'sparse'? Why function 'sparse' is not supported by Matlab compiler? ps: matlab 2015b +vs2015

According to the Release Notes for MATLAB Coder (which I believe is what you're using, not MATLAB Compiler) support for generating code using sparse matrices was introduced in release R2018a.

Hi,Steven.Thanks for your answer.But I do use Matlab Compiler ,which is called by the command line 'deploytool'.

Generating C++ DLL is MATLAB Compiler SDK if the DLL relies upon MCR being present, and is MATLAB Coder if the DLL is to be stand-alone (that is, not require MCR to be present.)

Yes,I have already installed mcr.
