Performing And Solving Limit Operations In MatLab®

Limit operations are very important in calculus and mathematics. In some cases, you need to calculate the limit operations by hand. But, you can also calculate limits in Matlab® easily.

You can perform your limit operations with the ‘limit()’ command in Matlab®. Here, we explain how to calculate limits with the ‘limit()’ command in Matlab®. Take a look at the very basic example below to understand the syntax of the ‘limit()’ command. 

How To Use ‘limit()’ Command In MatLab®?

>> syms a 
x = limit(a^2-3*a,a,1,'left')
y = limit(a^2-3*a^3,a,1,'right')
x =
y =

In the very basic example above, we created a symbolic variable ‘a’ with the syms command to use this variable in limit operations. 

Then we assigned the ‘limit()’ command to variable ‘x’. Then we typed our equation inside ‘limit()’ by using the symbolic variable ‘a’. You need to write your equation with Matlab® syntax. 

The second thing that comes after the equation in the ‘limit()’ command is the variable that you want to calculate limit operation, which is ‘a’ here. 

The third thing that comes right after the variable is the point on ‘a’ axis that limit will be performed. 

And the last one is the limit direction can be ‘left’ or ‘right’

Two examples are coded in the command window, check the results! 


Performing limit operations in Matlab® is very simple with the ‘limit()’ command as you see above.
