Adding zeros to matrix

7 次查看(过去 30 天)
I have to do image processing. I have one data with 100 x 100 matrix and another with 300 x 300 matrix. I want to add zeros to 100 x100 matrix to equalize it like 300 x300 but zeros to be added after 100 x 100 equally and not in particular end.

% Replace this with your image
Image100 = peaks(100)+10;
%Centering padding in 4 sides
PadImage300 = zeros(300,300,size(Image100,3),class(Image100));
PadImage300(101:200,101:200,:) = Image100;
imagesc(PadImage300)

Let A be your 100*100 matrix.
B = zeros(300) ;
B(1:100,1:100) = A ;

A = rand(2) ;
[m,n] = size(A) ;
B = zeros(3*m,3*n) ;
B((m+1):2*m,(n+1):2*n) = A ;

Yes this worked..!!!
Thank you.
Unfortunately I dont have Image toolbox so cant use padarray otherwise it could be easy.
