I have a matrix with 3 rows want to increase it to 5

how sould i do it ?

A=[1,1.2,1.4,1.6,1.8;1.3,1.6,1.7,2,2.2;1.8,2,2.5,2.6,2.7]

i want to keep the min amd max value as it is and the values in between should be interpolated

what's your desired result?

first and last row would be same but the remaing rows would be interpolated

What about:

A = [1,1.2,1.4,1.6,1.8; ...
     1.3,1.6,1.7,2,2.2; ...
     1.8,2,2.5,2.6,2.7];
n = 7;
B = interp1(1:size(A, 2), A.', linspace(1, size(A, 2), n))
