@Taniya is not a person like that. In her past questions, there were codes supplied.

@John D'Errico I want to know how the equation can write in matlab, as when i try it by writing sum it was not considered the summation.

Hi @Taniya

Are you trying to deal to the equation symbolically?

Or, are you trying to numerically compute the values of

and its derivative

using the for-loop method?
