MATLAB: How to create a vector of submultipliers

beginnerfactoringMATLAB

I want to write some code so that, when I enter a number, I get a vector composed of his sub-multiplier:

example: x=10; vector= [1,2,5,10]

how do you program such a thing?

Best Answer

x = 100;
v = (x./(1:x));
v = v(ceil(v)==v)

No need for a loop:

    positive_numbers = v(v>0);
    negative_numbers = v(v<0);
    zero_numbers     = v(v==0);

See "Logical indexing"

--- Example based on Comment 1 and 2 ---

In your code in the comment you overwrite the variables with identical results a number of times. I meant "No loop needed".

I misunderstood your question. I thought you wanted separate the positive values from the negative values. DOUBLE in the example below communicates the intent. Matlab doesn't need it.

Run this code as is (without a loop)

    v = [ 1, 5, -3, 0 ];
    positive_numbers = v(v>0);
    negative_numbers = v(v<0);
    zero_numbers     = v(v==0);
    numbers_of_positives = sum( double( v>0 ) );
    numbers_of_negatives = sum( double( v<0 ) );
    numbers_of_zeros     = sum( double( v==0 ) );

This certainly doesn't serve as an exercise with loops, but it returns a result.
