I have a following function that begins with:
function X=mFunction(alpha,beta)
%%load the dataset
filename = 'Bo_1.xlsx';
y = xlsread(filename);
yS=y(1:288);
I want to minimize it. But without load data every time..
How I should proceed?
Thanks!

You said you wanted to minimize it, so I just threw out everything that wasn't absolutely needed for the function to run. You assign a filename and read in a workbook but don't actually return it to your calling function, so I got rid of that unneeded part. From your comment later to Walter it sounds like you don't even know what alpha and beta are, so you might not need those either, and the function could be simplified even more - just don't have any input arguments. Now you'll have a function that does absolutely nothing - about as minimal as you can get.

Ok Image Analyst, it is very interesting what you say I'll take it in concideration. Thanks!

function run_my_plot
alpha = ....
beta = ....
filename = 'Bo_1.xlsx';
y = xlsread(filename);
yS=y(1:288);
X = arrayfun(alpha, beta, yS);
surf(alpha, beta, X, 'edgecolor', 'none');
function X = mFunction(alpha, beta, yS)
.... code with no load() goes here

That is a question that has nothing to do with this topic. Fortunately you have already opened a new Question about it, which has been replied to.
