ismcc

Test if code is running during compilation process (using mcc)

Syntax

x = ismcc


Description

x = ismcc returns true when the function is being executed by mcc dependency checker and false otherwise.

When this function is executed by the compilation process started by mcc that runs outside of MATLAB^® in a system command prompt, it will return true. This function will return false when executed within MATLAB as well as in deployed mode. To test for deployed mode execution, use isdeployed. This function must be used in matlabrc or hgrc (or any function called within them, for example startup.m) to guard code from being executed by MATLAB Compiler™ (mcc) or MATLAB Compiler SDK™.

In a typical example, a user has ADDPATH calls in their MATLAB code. These can be guarded from executing using ismcc during the compilation process and isdeployed for the deployed application in startup.m, as shown in the example on this page.

Examples

`% startup.m
    if ~(ismcc || isdeployed)
       addpath(fullfile(matlabroot,'work'));
    end 

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

• Returns true and false as appropriate for MEX and SIM targets.

• Returns false for other targets.
