create random number generator 2x2 in matlab

In order to create a 2x2 matrix with random numbers, you can use the rand function in Matlab. Simply specify the dimensions of the matrix in parentheses directly following rand. Here is an example:

main.m
rng('shuffle'); % seed the random number generator
rand_matrix = rand(2,2)
75 chars
3 lines

The rng function is used to "seed" the random number generator with the current time, ensuring that each time you run the script, you get a different set of random numbers. Of course, if you want to generate the same set of random numbers each time, remove the rng line.

You can also specify the range of the random numbers generated by rand using optional arguments. For example, to generate random numbers in the range [0, 5], you can modify the previous code as follows:

main.m
rng('shuffle'); % seed the random number generator
rand_matrix = rand(2,2) * 5
79 chars
3 lines

This will multiply each random number by 5.
