Hi,

Suppose the length of t is 1922 (size is 1922 1) and I want extract from (700:1900), then how I can do it?

similarly an other array P is also function of t with size (1922 1), so how can I extract corresponding values of P with reference to t. like P(700:1900), I mean same size of t.

在 MATLAB Online 中打开

t(700:1900)
P(700:1900)

Really, this is pretty basic stuff. I suggest you review Accessing Array Elements.

Oh, thanks, actually I confused with length, like P = length(t)
