MATLAB MATLAB trouble with reshape and random matricies

  1. Jun 16, 2013 #1
    I am trying to learn MATLAB with MIT OCW and I am running into some trouble.

    It says as an assignment:

    c. cMat = a 10x10 matrix where the vector 1:100 runs down the columns (use reshape).


    1 11 21.....91
    . ..............

    is the matrix I am trying to make and another exercise says

    f. Make fMat be a 5x3 matrix of random integers with values on the range -3 to 3 (use rand and floor or ceil)

    I am not sure how it wants me to go about these, thanks for any help. The course link is listed below.

    Figured it out. It took me a while though, sadly.

    for c. I used

    cMat= linspace(1, 100)
    cMat= reshape(cMat,10, 10)

    and d. I used

    fMat= ceil(rand(5,3)*10);
    mod(fMat, 4)

    And I really appreciate the help I am learning it through the MIT slides alone, I find I get hung up on little things like this.
