Your dimensions are not compatible to obtain an m-by-n result; your v2 should have dimensions {1,n}. The kernel function Dot then will calculate the matrix product. Example: v1 = { {2}, {4}, {6} }; v2 = { {1, 3 }; v1 . v2 On 1/28/2011 6:11 AM, EF wrote: > Hi, > > is there a "simple kernel based" routine to do the scalar product of two > one dimensional vectors, producing the m,n Matrix: > > v1[m,1].v2[n,1] -> mat[m,n] > > > > Thanks E.F. > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
