Passing mixed

orientation vectors to

interpn:

interpn(x1,x2,...,xn,

V,

x1q,x2q,...,xnq)

Specifically, if one or

both of the following

are true:

• x1,x2,...,xn are

a combination of

row and column

vectors.

• x1q,x2q,...,xnq

are a combination

of row and column

vectors.

Still Runs Construct the full grid with

ndgrid first. Alternatively,

use griddedInterpolant if

you have a large data set.

Modify all instances that

pass mixed orientation

vectors to interpn. You

can modify your code in one

of two ways:

• Call ndgrid to

construct the full grid

first.

[X1,X2,...,Xn]=

ndgrid(x1,x2,...,xn);

[X1q,X2q,...,Xnq]=

ndgrid(x1q,x2q,...,xnq);

Vq=

interpn(X1,X2,...,Xn,

V,

X1q,X2q,...,Xnq);

• Pass the vectors to

griddedInterpolant

inside a cell array.

F=

griddedInterpolant({x1,

x2,...,xn}, V);

Vq= F({x1q,

x2q,...,xnq});
