Christof

Function: christof (<dis>) A function in the ctensor (component tensor) package. It computes the Christoffel symbols of both kinds. The argument <dis> determines which results are to be immediately displayed. The Christoffel symbols of the first and second kinds are stored in the arrays lcs[i,j,k] and mcs[i,j,k] respectively and defined to be symmetric in the first two indices. If the argument to christof is lcs or mcs then the unique non-zero values of lcs[i,j,k] or mcs[i,j,k], respectively, will be displayed. If the argument is all then the unique non-zero values of lcs[i,j,k] and mcs[i,j,k] will be displayed. If the argument is false then the display of the elements will not occur. The array elements mcs[i,j,k] are defined in such a manner that the final index is contravariant.
