Hi guys
I am trying to understand a code from a book (I write few lines).
DO
f(1, = Fcn(x, y)
DO i=2, s
w = y + h*MATMUL(a(i, 1:i-1), f(1:i-1, )
f(i, = Fcn(x + c(i)*k, w)
END DO
END DO
It is clear for me the meaning of a(i, 1:i-1) but i did not find anything for f(1, , that is, when you have only :
Thanks in advance
