Insufficient number of outputs from right hand side of equal sign to satisfy assignment

This error can happen on many occasions. For example :
Suppose we have the following function :
[a,c,d]= myFun(x,y)


This function has three output that the user must specify when calling this function.

now, if the user use the following command by mistake,

[a,k]=myFun(6,11)

MATLAB will produce an error which means the number of outputs from the right-hand side of the equal sign does not satisfy the assignment.
