Changes To conv
The conv function now accepts the shape parameter as input.
Changes To conv2 and convn
Use of the conv2 and convn functions with one empty input now returns the matrix of the
correct size as described by the shape input.
Compatibility Considerations
Use of the conv2 and convn functions with one empty input no longer returns an
empty matrix. Instead, it returns the matrix of size specified by the shape input. For
information on how to use the shape input, see the reference pages for the conv and
conv2 functions.
nextpow2 Changing to Element-By-Element Calculation in a Future
Release
Compatibility Considerations
nextpow2 with a nonscalar produces a warning:
Warning: NEXTPOW2(X) where X is non-scalar will change
behavior in future versions: it will operate on each element
of X. To retain current behavior, use NEXTPOW2(LENGTH(X)) instead.
This behavior will change in a future release. Replace instances of nextpow2 with
nonscalar input X to nextpow2(length(X)) to maintain the current behavior.
Function finite Being Removed
The finite function is obsolete. Use of the finite function now causes an error in
MATLAB.
Compatibility Considerations
Replace all instances of finite with isfinite.
