Common Mistakes

Using the numbers directly instead of variables.

Swapping the order of inputs.

The mod function returns the remainder of division. Use the variables a and b as inputs.

💡 Hint

Common Mistakes

Using ^ instead of .^ which causes an error for vectors.

Using multiplication * instead of power operator.

In MATLAB, .^ is the element-wise power operator. To square each element, use .^ 2. The multiplication operator * is not used here.
