How to change the scaling back to negative values after applying accumarray function?

3 Ansichten (letzte 30 Tage)
I had to impose the accumarray function on two variables, C12 and S12. S12 had negative numbers up to -89 so I had to modify the accumarray function, and input it instead as:
A = accumarray([C12+1, S12+90], 1);
mesh(A)
My question is: now that I plotted the values, how to I change the values of S12 back to their original values within the plot?

Well, if this question is redundant and the discussion happens in the other thread, maybe it ought to be deleted?

I agree, but I’ll leave that decision to jgillis16. This thread began during the night for me (GMT-6), so I didn’t know then it had posted.

Wouldn't
mesh(S12, C12, A)
work?

C12 - 179 x 361 double
S12 - 179 x 361 double
A - 361 x 179 double

How does accumarray work if C and S are 2D and with that many columns?
Wasn't your code
A = accumarray([C12(:)+1, S12(:)+1], 1)
rather?
Anyway, I didn't think this through properly, this should work (assuming the above A):
mesh(min(S):max(S), min(C):max(C), A)
Basically, you just want to pass to mesh the original range of your S and C.
