Using a text file as a function parameter

I am trying to create a function where the inputs are text files. For some reason, the program is not reading the files, I am getting the message "Reference to a cleared variable input A".

function [result] = funtion_name(InputA,InputB,InputC);
clear all
VariableA= dlmread(InputA);
VariableB= dlmread(InputB);
VariableC=fileread(InputC);

%Do something

end

MATLAB is case sensitive. inputA is not the same as InputA

This is not the problem. In my code, I checked if I was consistent with the variable names.

clear all

clears all variables. At the start of any function it is totally counter-productive cargo-cult programing:

Thank you. It worked!

The "clear all" is clearing the input parameters.

You should never use "clear all" inside a function. If you use it at all inside a script, it should be reserved for a script that does nothing but reset the state of MATLAB, to be used only under circumstances where you might otherwise close MATLAB and restart it.

I deleted "clear all", now it works. Thank you.
