Execting one Matlab file using another

Question

This might be a pretty basic question but I was not able to find an answer for this.

I am trying to run a matlab code that has two arguments passed to it :
1. Name of an existing matlab code
2. An integer number.
This would be the command I would run in the command window in Matlab-

>> auto_caller mytest.m 10

Here auto_caller is the main code and it should execute the file mytest.m 10 times.

This is what I tried -

function [arguments] = auto_caller(filename, iterations)
    for i = 0 : str2num(iterations)
         filename
    end
end

But when I run it, the output is just -

mytest.m
mytest.m
mytest.m
mytest.m
mytest.m
mytest.m
mytest.m
mytest.m
mytest.m
mytest.m

Can someone help me to solve this problem?
Thanks,
Shreedhar

Instead of passing the name of the matlab source file containing the function, pass a function handle:

auto_caller @mytest 10

This is the same way that Mathworks-provided optimization algorithms accept goal functions, GUI widgets accept event callback functions, etc.

A simple solution:

Use run(scriptname_here)

I never knew there was a run function. +1 for teaching me something new

FWIW, run is just a wrapper for evalin and cannot accept input arguments.

@excaza that is interesting as well. thanks for that info.

You can call a file by using the eval function

function runScript(file,n)
    for i = 1:n
       eval(strrep(file,'.m','')) 
    end
end

'eval' works for me!! In fact I tried all the answers and they all work.

However, in the loop, we need to convert the value of n into number. str2num. Because using n as it is gave me an error.

with the way you are passing values into the function, yes you would need to convert it. I was assuming you could call the function as runScript('somefile',10)
