Function to store values??

Which would be a function to store values from a loop?

For example

I want to get a random number from 1 to 100

I get any number and i want to store that number in a vector

Choose any other random number again

And I want to store that number with the last one I got

And repeat

I just want to know which function to use

Im bad a coding and idk how to explain more clearly :((

You wouldn't do it with a loop. There's a command for it,

result = randi(100,1,5)

result = 1×5

95 75 86 82 56

I suggest going through MATLAB Onramp. Ch 5 and Ch 13 are probably of particular relevance here.

Not sure what "store that number with the last one I got" means. Do you want a 2 column array with column 1 being the first number and column 2 being the second number? Matt's solution about using rand() is good and for 2 columns you'd do this:

numRows = 40; % Whatever
randomValues = rand(numRows, 2);

If you insisted on using a loop to build it, then you'd do this:

numRows = 40; % Whatever
for row = 1 : numRows
    randomValues(row, 1) = rand(1); % Generate a single random number and store in column 1.
    randomValues(row, 2) = rand(1); % Generate a second single random number and store in column 2.
end

Or if you wanted two vectors instead of a matrix, you could do

numRows = 40; % Whatever
for row = 1 : numRows
    vec1(row) = rand(1); % Generate a single random number and store in vector vec1.
    vec2(row) = rand(1); % Generate a second single random number and store in vector vec2.
end
