interp1(X, Y, Xq,

[], ...) where []

specifies the default

interpolation method

Still Runs interp1(X, Y, Xq,

'linear', ...)

Replace all instances

of interp1(X, Y,

Xq, [], ...) with

interp1(X, Y, Xq,

'linear', ...).

Passing mixed-

orientation vectors to

interp2:

Vq = interp2(x, y,

V, xq, yq)

Specifically, if one or

both of the following

are true:

• One of x and y is a

row vector and the

other is a column

vector.

• One of xq and yq is

a row vector and the

other is a column

vector.

Still Runs Construct the full grid

with meshgrid first.

Alternatively, use

griddedInterpolant

if you have a large data

set.

Modify all instances

that pass mixed-

orientation vectors

to interp2. You can

modify your code in one

of two ways:

• Call meshgrid to

construct the full

grid first.

[X,Y] =

meshgrid(x, y);

[Xq,Yq] =

meshgrid(xq,

yq);

Vq = interp2(X,

Y, V, Xq, Yq);

• Pass the vectors to

griddedInterpolant

inside a cell array.

F =

griddedInterpolant({x,

y}, V.');

Vq = (F({xq,

yq})).'
