Convert the matrix into an image. Display the maximum and minimum values of the image. K = mat2gray(J); min_image = min(K(:)) min_image = 0 max_image = max(K(:)) max_image = 1 Note that values are still data typedouble, but that all values are in the range [0, 1]. ...

Step 1 Define a matrix in a standard way, if you haven't already done so, by typing for example the following: A = [1 2 3; 4 5 6; 7 8 9; 5 5 5]; Video of the Day This code creates a matrix 'A' that is four rows by three columns. Step 2 Count the number of elements...
Example:pcfromdepth(depthImage,depthScaleFactor,intrinsics,DepthRange=[0,Inf])sets the depth range to the 2-element vector value of[0,Inf]. ImagePoints—Image points [](default) |M-by-2 matrix Image points, specified as anM-by-2 matrix of [xy] coordinates, whereMis the number of points...
imwrite(A,map,filename) writes the indexed image in A and its associated colormap map to the file specified by filename. If A is an indexed image of data type double or single, then imwrite converts the indices to zero-based indices by subtracting 1 from each element, and then writes...
Convert a numeric matrix to a character vector, to three digits of precision. chr = mat2str([3.1416 2.7183],3) chr = '[3.14 2.72]' Convert Integers Create an array of integers and convert it to a character vector. By default, the output ofmat2strrepresents an array of doubles. To re...
The syntax of "R = i(:, :, 1);" means that you are creating a new matrix R and setting it equal to all the rows and columns of the first layer in image i (hopefully that makes sense). You then create a new image containing all zeros of the same size as the original. After ...
Convert the matrix to full storage. The MATLAB display of the matrix reflects the new storage format. A = full(S) A =8×80 0 0 0 0 0.9502 0 0 0.0344 0.4387 0 0 0 0 0 0 0 0 0 0 0 0 0.3816 0 0 0 0.7655 0 0 0 0.7952 0 0 0 0 0 0 0.1869 0 0 0 0 0 0 0 0 0 ...
