I read a function file and save it in a cell array. I modified the content of the cell array that contains each line of the function. I then saved it in another function file. Can I immediately execute the newly saved [function] file given some input values. I tried it and intend to save the output of the function in a matrix, it seems like I get same result always (which is wrong) based on the content of the matrix after executing a loop. Please advise me on what to do to have normal and accurate result on executing the immediately written function file.

After you save a function to a .m file, you should "clear" the function name to remove any cached code of the function.

It worked! I have spent months trying to fix this bug. I kept on getting results for iterations 2 and above as if the variable or the file is sticking to previous contents. Thanks Walter Roberson.

Do you save it in a different file name (and function name)?

If NO, then its highly likely that your old file gets executed (especially if its higher on the path or in the current directory).

Yes, I save it in a different file name. But the function name still carries the old file name. For example, the old file name is sumOfRoots.m which contains a function with name sumOfRoots(inputs). Now the new file is called (e.g. newFile.m) but with the function name sumOfRoots(inputs). What I want is actually to be able to execute the new file and see the effect of the changes I made to the original file. Thanks @J Smith.
