Run MATLAB script - MATLAB run - MathWorks Amrica Latina Is there a way to call the function like. In this particular example, repeated calls to eval this string will likely be less efficient than repeated calls to the equivalent function handle (MATLAB's JIT compiler has no way to optimize the code hidden in a string, but it certainly can with a properly defined function handle called with properly defined input arguments). Since Matlab version 2016b, you can use the built-in strip() function.. For those who do not have the newer matlab version, here is my self-defined function, which also does not have the limitation of exact one char when strCharacter is passed in as strip() MATLAB considers all variables as arrays .
