I have to apply a set of equations to each row of a matrix. For instance, the first row is y of the verb while the second row is x. The results of the verb are then used with the third row and so on through the matrix. At the same time, the verb is accessing another matrix which the same dimension as the first one, with each row of it being used by the verb as the calculations move through the matrix. I have tried using v / which is great but I can't see how the verb will access the rows of the second matrix. I am currently using the FOR_MATRIX .. DO.END structure which works fine but I wonder if there is a more efficient way in J to undertake recursive calculations through rows of a matrix in this manner.
