In Matlab, does a
pad command exist, which also pads in the negative dimension
(therefore removing indices in a specified dimension)?
[Edit: I knew something did this -
fft does this for the input, but it also takes the
I have a function which can receive input data
I would like to remove all but
n datapoints from a user specified dimension
I could use
shiftdim to always make the specified dimension the first dimension;
however, how do I code such that I do not need a finite number of colons
to represent the dimensions of the input data
x = rand(01,12,01); % n_dim = 1 y = rand(04,12,01); % n_dim = 2 z = rand(04,12,07); % n_dim = 3 n = 3
dim = 1 y = y(1:n, : ); z = z(1:n, :, : ); % Note that extra colons are needed depending on n_dim.
dim = 2 x = x( 1:n ); y = y(:, 1:n, ); z = z(:, 1:n, : ); % Note that extra colons are needed depending on n_dim.
Do I need to use the
shiftdim command to place
dim in the first dimension,
and then place the
1:n within the
along with a
string variable which contains as many
,:s as needed?
