Use "reshape" function, Warn : the number of elements must not change means for your initial image I of size(n,p), the number p*n=2500 :
Resized=reshape(I,50,50);
if n*p!=2500, try to truncate elements ,
Is that what you mean?

imresize() is part of the Image Processing Toolkit. Do you have access to that? It is optional (extra cost) for the Academic and Professional version, but is included in the Student Version, but might not be installed by default.

hi, did you try my first answer using reshape ?
You can try other methods , such as down_sampling like if you have an Image I of size 400x400 you can downsample it :" I=I(1:8:end,1:8:end)"
% Given your image I of size(m,n)
m=250;
n=250;
I=rand(m,n);
mm=floor(m/50);
nn=floor(n/50);
J=I;
J=J(1:mm:end,1:nn:end);
% Now you new image J is of size 50x50
