PROCEDURE: TDOTP Purpose: Vectorized routine to calculate the dot product of two tplot variables containing arrays of vectors and storing the results in a tplot variable Arguments: v1: The name of the tplot variable storing the first vector in the dot product v2: The name of the tplot variable storing the second vector in the dot product newname(optional): the name of the output tplot variable error(optional): named variable in which to return the error state of the computation. 1 = success 0 = failure NOTES:
