create a picture with matrix
显示 更早的评论
Is it possible to create a black&white image from a matrix with 0 and 1? for example, matrix 50x25 (each element represent a pixel) randomly filled with 0 and 1 (assume black = 0 and white = 1), then use that to draw a picture.

Here's what I understand from your question, you have a matrix of 0s and 1s and want to generate a binary (black and white) image.
You can convert any 2d matrix to grayscale (black and white) image using 'mat2gray' function
And since your matrix only contains 0 or 1 so your image would contain only black or white, no gray levels.
