Hello everyone.I have a question about an matrix.I want to a interpolation in M(10X2 double)' datas.And I want to obtain the N(9X2) matrix.Here you can see the example
time step variables time step variables
M=[ 3.2 5 N= [4 ...?
4.1 4 5 ...?
5.6 3 6 ...?
6.7 2 7 ...?
7.5 1 8 ...?
8.4 3 9 ...?
9.3 2 10 ...?
10.5 5 11 ...?
11.4 2 12 ...?]
12 6]
Thanks for your answer !!!

Try this —
M=[ 3.2 5
4.1 4
5.6 3
6.7 2
7.5 1
8.4 3
9.3 2
10.5 5
11.4 2
12 6]
N = [4; 5; 6; 7; 8; 9; 10; 11; 12];
N2 = interp1(M(:,1),M(:,2),N)
N = [N N2]
.

My pleasure!
I created ‘N’ using the original ‘N(:,1)’ as the first column, and the interpolated values as the (second) ‘N(:,2)’ column, as described in the original post.
Do the same with your (3015x1) vector.
