interp1q Still Runs interp1 Replace all instances of

interp1q with interp1.

interp1(...,

'cubic')

Still Runs interp1(..., 'pchip') Replace all instances of

interp1(..., 'cubic')

with interp1(...,

'pchip').

Passing nonuniformly

spaced points or grid to:

interp1(..., 'v5cubic')

interp2(..., 'cubic')

interp3(..., 'cubic')

interpn(..., 'cubic')

Warns

interp1(..., 'spline')

interp2(..., 'spline')

interp3(..., 'spline')

interpn(..., 'spline')

In previous releases,

interp1, interp2, interp3,

and interpn silently

changed the 'v5cubic'

and 'cubic' methods

to 'spline' when the

sample data was not

uniformly spaced. Now,

a warning is issued if the

uniformity conditions are

not honored. To avoid the

warning message, change

any instances that call

for'v5cubic' or 'cubic'

to the 'spline' method.

Passing the 'pp'

flag to interp1. For

example:

pp = interp1(x, v,

'linear', 'pp');

vq = ppval(pp,

xq);

Still Runs Use griddedInterpolant

to create an interpolating

function that is efficient

to evaluate in a repeated

manner.

Replace all instances

of interp1(...,

'pp') with

griddedInterpolant.

For example:

F =

griddedInterpolant(x,

v, 'linear');

vq = F(xq);
