Hello I want to interpolating between variables as below: x=matrix with 2×54 dimension and y=matrix with 1×54 dimension and x_q=matrix or vector with 2×1 dimension. Is it possible to use interp1 or interp2 functions?

在 MATLAB Online 中打开

F = scatteredInterpolant(x(1,1:54),x(2,1:54),y(1,1:54));
y_q = F(x_q(1),x_q(2))

Thank you dear friend. problem solved with your suggestion. But the inputs must be specified in column-vector format.

If understood your question correctly, in this case - you're trying to interpolate with 1-by-54 of y using 2-by-54 of x. if this is the case, you'd need to have matched sizes for x and y. Otherwise, it does not make quite much of a sense.
