The first part of the marked answer is the correct answer for this particular question, but Google brought me here and this is actually what I was looking for, searching: "javascript access a function inside a function." You want to put the nested function inside another function (as the term nested implies) and then call the top-level function. As an example, create the following file, evenodd.m function [even, odd] = evenodd(x) In Matlab terminology what you have there is a local function. Local Functions are extra functions defined within a function m-file, appearing after the end of the "main" function. Local functions have a separate workspace i.e. to use variables from the main function they will need to be inputs to the local function Your two functions are in two different Mfiles. If these are functions you should ensure that the function and Mfile names are the same. Then you can simply call one function from the other one (assuming that they are both on the MATLAB search path). Any variables that you create within a function are stored within a workspace specific to that function, which is separate from the base workspace. Program files can contain multiple functions. If the file contains only function definitions, the first function is the main function, and is the function that MATLAB associates with the file name. I have two matlab script files .m (not function files) and if I want to call another script in my current script, which command should I use? call a matlab script in a script. Ask Question Asked 8 years, 6 months ago. Active 2 years, how to call a user defined function in matlab in that is the function. i haven't defined an input in this function because *in my scenario, my GUI requires an input from the user and when i type in a number and press calculate the pushbutton which is 'calculate' should look at the user input for instance it is the variable 'h'and perform the function above and display the warning messages accordingly * Leonard - I'm pretty sure that you can't do that. If your m-file is named AllFunctions.m, then either it is a script that you can run or it is a function which has the same name as the file which you can call (passing in arguments, getting a result, etc.), but you cannot access any other function that has been defined in that file.
