Could anyone help me ,How can i interpolat my data Q1(37*1),Q2(38*1),depth(0:5:25)
I Created a new depthe D ,and when i use this code >>
X = interp1 (D, Q2, depth, 'linear');
y = interp1 (D, Q1, depth, 'linear');
showing this error
Error using griddedInterpolant The grid vectors do not define a grid of points that match the given values. Error in interp1 (line 183) F = griddedInterpolant(X,V,method); thank you ....

Your ‘D’, ‘Q1’ and ‘Q2’ vectors have to be the same length. You have to decide how to equalize them.
It is probably easier to create ‘D’ as (37x1) and remove one point (probably Q2(end)) from ‘Q2’.
If ‘depth’ uses values outside the range of ‘D’, remember to specify a method (for example 'linear') and use the 'extrap' option.
