MATLAB: Array slicing scattered rows

array slicingscattered rows

How can I select scattered rows from an array? Suppose

A = rand(6,6)

now how can I select everything except the second and fifth row of A?

You can use setdiff()

A = rand(6,6);
idx = setdiff(1:size(A,1), [2 5]);
B = A(idx, :);

To slice the variable 'a', you need to use a subscript list that contains:

So, for example, in the following case, 'a' will be a sliced output:

parfor n = 1:35
  tmp = 90 * ones(1, 15);
  a(n, :) = tmp;
end

which creates 'a' as a 35x15 matrix with each element containing the value 90.

use the vector slicing to get one slice, Let V is the input volume. e.g

S=V(:,:,1);

use 'imshow' or 'imagesc' functions to view the slice as image
