Dear all,

I can't wrap my head around this. Mathematically it's not hard, I just 
don't know how to store and access it without many loops.

I have a function f(x,y).

I would like to calculate it at x = arange(20,101,20) and y = arange(2,30,2)

How do I store that in a multi-dimensional array and preserve the grid 
points where I did the calculation so that I could plot later groups of 
function plots like this:

for elem in y-values
plot(x_values, f(x,y=elem)

or
for elem in x-values:
plot(y_values, f(x=elem,y)

I can smell that the solution can not be so hard, but I currently 
understand how to keep the points where I did the evaluation of the 
function.

Maybe it is also imaginable to do something with functional tricks as 'map'?

Thanks for any suggestions!

Best regards,
Michael
