# VosejkProduct

VosejkProduct(Expression,jStart,jFinish,kStart,kFinish,Jincrement,kIncrement, NonVolatile)

Example model

This function calculates the following expression:

for a certain function f(j,k).

• Expression - the equation to be summed in string form, i.e. within " ", with the labels j and k representing the variables to be multiplied over

• Jstart - the minimum value of j at which the product is to begin

• Jfinish - the maximum value of j at which the product is to end

• Kstart - the minimum value of k at which the product is to begin

• Kfinish - the maximum value of k at which the product is to end

• Jincrement -optional parameter (default = 1) that allows one to specify that the summation is over non-integer increments of j.

• Kincrement -optional parameter (default = 1) that allows one to specify that the summation is over non-integer increments of k.

• NonVolatile - an optional recalculation mode parameter. If set to TRUE the function is evaluated only at the moment it is entered. If set to FALSE (default), the function is re-evaluated on each spreadsheet recalculation.
