I keep getting an error every TIME i RAN THIS LOOP: %loop
M(:,:,:,1)=M1;
M(:,:,:,2)=M2;
M(:,:,:,3)=M3;
YC(:,:,1)=YC1;
YC(:,:,2)=YC2;
YC(:,:,3)=YCC3;
[M1]=ProbabiltyCounty1( X,Lam ,YC1)
[M2]=ProbabiltyCounty1( X,Lam ,YC2)
[M3]=ProbabiltyCounty1( X,Lam ,YCC3)
for i= 1:3;
for j=1:3;
YC= YC(:,:,i);
MatrixM= M(:,:,:,j);
end
end
FinalOutput= [MatrixM]
AYesIdiditNow2=[FinalOutput];

This line:
YC= YC(:,:,i);
replaces the original multi-page YC with only one page of YC the first time through the loop. So the next time through the loop when i>1 the YC(:,:,i) is referencing pages that are no longer there.

Hey James, Thanks for your answer. I am failry new to Matlab and my struggles are real! What do you mean by multi-page? Thanks

In "array terminology", a 2-dimensional (2D) array is referred to as a "matrix". An array having more than two dimensions is often referred to as a multi-dimensional array, or nD array. In this latter case, the first two dimensions of such an array are often referred to as the "pages" of the array (i.e., the nD array is made up of multiple 2D "pages"). E.g., a 3x2x5 dimensional array can be thought of as 5 pages of 3x2 matrices.
