# Factorial Calculation In MatLab

Factorials are very important aspect of calculus. And engineers are generally calculates calculus problems in Matlab. You can calculate the factorials of various kinds of vectors and matrices in Matlab easily with ‘factorial()’ command in Matlab. In here, we explain how to calculate the factorials in Matlab with ‘factorial()’ command.

## How To Use ‘factorial()’ Command In MatLab?

``````a = [2 6 3 6];
b = [5 3 4 6; 4 6 3 6; 4 8 9 3];
x = factorial(a)
y = factorial(b)
z = factorial(10)``````

As you see in above code in Matlab, we created a vector called ‘a’ and a matrix called ‘b’. The use of ‘factorial()’ command is very simple as you see. Just write the thing inside paranthese of factorial() command to calculate its factorial.

You can assign the factorial() command to a variable, or you directly calculate different factorials in command window of Matlab by writing it without asignment.

``````x =

2   720     6   720

y =

120           6          24         720
24         720           6         720
24       40320      362880           6

z =

3628800``````

You can see the results above in Matlab Command Window. The factorial calculation of vector ‘a’ is done for all elements respectively. The same thing is valid for also matrix ‘b’.
