MATLAB: How to run m-files(main function is variable) with Matlab code

run function name

The values of variable have been got by excel file. And also known the name of m-file for the main function. I want to call this main function with variable or others instead of type the function name directly.
for example
below inputs already defined.
a1=1;
a2=2;
a3=5;
b1=6;
b2=9;
...
Question is how to run the m-file with above inputs value? i try to use
run myfun
but error happen due to variable a1, a2, …b2 don't be assigned with above values.
I know we can use below comen code. but it is not what I want because there are many different m-file. I want to make a general coe to replace below code. I don't want to copy below code flow and past it every time for too many m-file.
[x1,x2,x3]=myfun(a1 a2 a3 b1 b2 )
below function is defined in myfun.m
function [x1,x2,x3]=myfun(a1 a2 a3 b1 b2 )
x1=a1+a2,
x2=a3+a2;
x3=b1+b2+b3;
end

Best Answer

You can use the cell array to expand the input arguments automatically. For example
argument_input1=5;
argument_input2=6;
...
argument_input30003=9;
Input_parameter={5 6 .. 9} % cell array
Call the function like this
S=myfun(Input_parameter{:})
