finddim
Find dimensions with specified label
Syntax
Description
Examples
Obtain Dimension with Specified Labels
Create a formatted dlarray
with some repeated dimension labels. Specify the dimension labels as 'TSSU'
. The dlarray
call reorders the labels, because it enforces the order 'SCBTU'
. For more information about dimension labels, see Usage.
dlX = dlarray(randn(5,4,3,2),'TSSU');
Obtain the dimensions with the label 'T'
.
dimT = finddim(dlX,'T')
dimT = 3
Obtain the dimensions with the label 'S'
.
dimS = finddim(dlX,'S')
dimS = 1×2
1 2
Obtain the dimensions with the label 'B'
.
dimB = finddim(dlX,'B')
dimB = 1x0 empty double row vector
Obtain the size of the dlX
dimensions labeled 'S'
.
SSize = size(dlX,finddim(dlX,'S'))
SSize = 1×2
