Find duty cycle of DC-DC buck-boost converter in Matrix

I need to calulate the duty cycle for buck-boost converter in matrix, I have code as following

vin = randi ([10 100], 1, 100000);

vout = randi ([100 1000], 1,100000)

D= vout/(vout-vin);

when I run the code it just give me one value so I need to know how get the whole value of matrix

when I do the following, D= vout/(vout-vin).

I got error says " Invalid use of operator"

You should use "./" instead of "/", this changes it to a vector operation instead of a matrix operation.
