“Matlab Error: Too many input arguments “

Hi everyone!
I'm a student using MatLab for research. Some of the formulas we work on are pretty complicated.
At times this error comes up. All the inputs were checked beforehand to be correct before they are entered.
Still, sometimes this error would not go away.
Does anyone with experience in MAtLAb have a solution to his?
Thanks a lot for any help!
