I have an equation that i want to implement in Matlab and it has the following symbol ∏ (used to denote Capital Pi or the product of a sequence of terms).

I want to know what is the matlab command for ∏?

what if i have limit as well, say from i=1 to 10?

E.g.,

 a=rand(1,100);
 p=prod(a(1:10))

prod computes the product of the elements of a vector or array. This is near to the definition of your Pi, but not exactly the same, e.g. you cannot define the limits equivalently.

I suggest to use the documentation to find out such solutions by your own. While the indexing methods are explained exhaustively (I love this term when I speak about Matlab's documentation) in the "Getting Stared" chapters, you can find the prod() function e.g. by:
