# Performing Derivations Of Equations In MatLab®

Derivations are very important in calculus or mathematics. In Matlab®, derivations are very basic with the ‘diff()’ command. Here, we explain how to use the ‘diff()’ command in Matlab® to perform derivations.

Take a look at the example below to understand the syntax and the use of the ‘diff()’ command.

## How To Use ‘diff()’ Command In MatLab®

``````>> syms a b
x = diff(3*a^6+7*a*b^5+3*a*b+3,a,3)

x =

360*a^3

>> ``````

As you can see above, we created two symbolic variables with the syms command to obtain our equation inside the ‘diff()’ command. Then we created our equation firstly inside ‘diff()’ as you see above. The equation must be created with the Matlab® syntax.

The second value inside the ‘diff()’ command above is the according to which variable, you will perform derivation, which is ‘a’ here.

The third term is the degree of derivation which is ‘3’ here.

You can directly see the answer in the command window above.

## Conclusion

As you see above, the use of the ‘diff()’ command to calculate derivatives in Matlab® is very simple.
