Dimension Expansion Toolbox
Listed below are some examples to demonstrate the power of the toolbox. For detailed usage please refer to the NDOP function in the toolbox.
(1) Expansion of SUM : Concept Study.
Y = ndop(@sum,X,DIM)
is equal to the usage of the common SUM function, but constitutes the concept the simplest way.
(2) Expansion of the DCT : First Usage.
Y = ndop(@dct,X,DIM,N)
expands the DCT to N dimensions, where DIM is the operating dimension, N the padding/truncating length and X the N-D array input.
(3) Exp. of INTERSECT : Binary Usage.
[C,AI,BI] = ndop(inf,@intersect,A,B,DIM)
is the INTERSECT function expanded for the usage of N-D arrays A,B, where DIM is the operating dimension.
(4) Demonstrating Trimlength Usage T,
by expanding the UNIQUE function
B = ndop(T,@unique,1,A,DIM);
A = [1,1,1;1,2,3]
(a) Maximum Trimlength T = inf
B = [1,NaN,NaN;1,2,3]
(b) Minimum Trimlength T = -inf
B = [1;1]
(c) Fixed Trimlength T = 2
B = [1,NaN;1,2]
