Syntax

y = stripdims(dlX)

Description

example

y = stripdims(dlX) returns the dlarray dlX without any labels.

Examples

Open Live Script

Create a labeled dlarray.

dlX = dlarray(randn(3,2,1,2),'SSTU')
dlX = 
  3(S) x 2(S) x 1(T) x 2(U) dlarray


(:,:,1,1) =

    0.5377    0.8622
    1.8339    0.3188
   -2.2588   -1.3077


(:,:,1,2) =

   -0.4336    2.7694
    0.3426   -1.3499
    3.5784    3.0349

Create an array that is the same as dlX but has no labels.

y = stripdims(dlX)
y = 
  3x2x1x2 dlarray


(:,:,1,1) =

    0.5377    0.8622
    1.8339    0.3188
   -2.2588   -1.3077


(:,:,1,2) =

   -0.4336    2.7694
    0.3426   -1.3499
    3.5784    3.0349

Input Arguments

collapse all

Input dlarray, specified as a dlarray object.

Example: dlX = dlarray(randn(3,4),'ST')

Output Arguments

collapse all

Unlabeled dlarray, returned as an unlabeled dlarray object that is the same as the input array dlX, but without any labels. If dlX is unlabeled, then y = dlX.

Tips

  • Use stripdims to ensure that a dlarray behaves like a numeric array of the same size, without any special behavior due to dimension labels.

  • ndims(dlX) can decrease after a stripdims call because the function removes trailing singleton labels.

    dlX = dlarray(ones(3,2), 'SCB');
ndims(dlX)
    ans =

     3
    dlX = stripdims(dlX);
ndims(dlX)
    ans =

     2
