Hello, I'm new to MATLAB and programming in general, so excuse my ignorance. I'm working on an optimization function that maximizes correlation between images by changing rotation and scale along with displacement. I don't have MATLAB's Optimization Toolbox but I do have the Image Processing Toolbox. I'm using the fminsearch function, but I don't know how to factor in multiple variables. Please review my code so far and let me know what I need to change and how so.

function corr= corrfun2(factors)

image1= imread('grid1.jpg');

image2= imread('grid2.jpg');

scale=factors(1)

rotate=factors(2)

corr= 1-normxcorr2(image1(100:200,200:300),imrotate(imresize(image2,scale),rotate));

[val,index]=min(corr);

[peakcorr,row]=min(val)

column=index(row)
