Error by having similar names for a variable and a MATLAB function

When the name of the output variable (max) is similar to the name of function (max), I get the error of "Unrecognized function or variable 'max'. Why does it happen?

function max = find_value
max = max([10 100]);
end

Thanks!

never use matlab function names as variables

you code should be

function max_value = find_value
    max_value = max([10 100]);
end

Hi,

In MATLAB, when you have a variable with the same name as a built-in function, MATLAB will use the variable instead of the function. To resolve this conflict, you can simply change the name of the output variable to something else. Please refer the following code for reference:

function max_value = find_value 
    max_value = max([10 100]);
end
