There are lots of kinds of mathematical functions in Matlab®. These mathematical functions can be very useful when they are used properly in Matlab® codes. In this article, we will explain how to calculate the absolute values of variables such as integers, vectors, and matrices in Matlab®.
>> a = [2 6 3; 45 36 3; 4 5 6]; b = [2 5 9 3 9 5 3 9]; c = 45; abs(a) abs(b) abs(c) ans = 2 6 3 45 36 3 4 5 6 ans = 2 5 9 3 9 5 3 9 ans = 45 >>
We created variables as ‘a’, ‘b’, and ‘c’ that are respectively matrix, vector, and an integer as shown above in Matlab®. Also, we respectively calculated their absolute values by typing them inside the parenthesis of abs() command. As you understand that the ‘a’ matrix all element’s absolute values are calculated individually as shown above.
Also, this is valid for the absolute value calculation of vectors. The whole elements of the vector ‘b’ absolute values are calculated individually. Also, the sign value of ‘c’ is directly calculated as absolute with abs() command as shown in Matlab®.
So the logic is very basic.
