In newer versions of MATLAB (R2015a and later) the easiest way to do this is using the repelem function: B = repelem(A, 2, 2); For older versions, a short alternative to the other (largely) indexing-based solutions is to use the functions kron and ones: >> A = [2 6; 8 4]; >> B = kron(A, … Read more
You are looking for the REPMAT function: x = [1 2 2 3]; m = repmat(x,4,1); You can also use indexing to repeat the rows: m = x(ones(4,1),:); or even outer-product: m = ones(4,1)*x; and also using BSXFUN: m = bsxfun(@times, x, ones(4,1))
I also got bitten by this problem. Very hard to diagnose, even harder to find similar reports and usable solutions. “Tapas” on the freenode #android-dev irc channel came with the following utility method: public static void fixBackgroundRepeat(View view) { Drawable bg = view.getBackground(); if (bg != null) { if (bg instanceof BitmapDrawable) { BitmapDrawable bmp … Read more
