So this is a very simple example of a technique that is used all the time in MATLAB where you will just take the results and store them in a matrix for easy manipulation and use later. This would also work if you were calculating a vector each time through the loop and wanted to ...
Than I could use arrayfun to define anamorphosis(i, :, :) as anamorphosis(i, :, :) = arrayfun(@find_color, i_orig_array, j_orig_array, double) but I get an error because double is a matrix and not a vector of the same size as I_orig_...
initialized matrix M2 with zeros of the same size as M1 and iterated over each element in M1 by converting the value to a two-digit hexadecimal string, then convert it to an index value. Finally, assigned the index value to the corresponding position in ...
Sum the Elements of a Matrix Using thesum()Function in MATLAB To find the sum of all the elements of a matrix, we can use thesum()function. In the case of a matrix, we have to use thesum()function two times, one for rows and one for columns, but in the case of a vector, we...
Generate Random Numbers Using the rand() Function in MATLAB If you want to generate uniformly distributed random numbers, you can use the rand() function in MATLAB, which generates random numbers between 0 and 1. You can also specify the size of the matrix containing random values, and each...
MATLAB is proprietary, closed-source software. For most people, a license to use MATLAB is quite expensive, which means that if you have code in MATLAB, then only people who can afford a license will be able to run it. Plus, users are charged for each additional toolbox they want to ...
