MATLAB: Repmat function give error

function cvgabortexturesegmentrun(imfilekMATLABoutfile)

can anyone help me please, when i run this line of code give me the following eroor :

Error using repmat Replication factors must be a row vector of integers or integer scalars.

Error in cvGaborTextureSegmentRun (line 28) imseg(idx, 🙂 = repmat(color(i, :), [], length(idx));

Are you sure it's repmat that you want? The calling syntax looks like you were trying to use reshape() instead. If you're sure repmat was intended, then this might be what you were trying to do,

   imseg(idx, :) = repmat(color(i, :), [length(idx),1]);

MATLAB: Determine combination of elements in matrix

You can use combnk() to create the permuted column indices for each row of your matrix and then replace those values by 0.

% Generate some data
z = ones(6,4);  % your original matrix
nzeros = 2;     % number of zeros to add to each row

Solution:

permIdx = combnk(1:size(z,2), nzeros); %permutation index
linIdx = sub2ind(size(z),repmat(1:size(permIdx),nzeros,1).',sortrows(permIdx)); 
z(linIdx) = 0;

MATLAB: Replicate values of a vector

Hi,

try repmat:

repmat(A,4,1)

Or for the other direction:

repmat(A,1,4)

In the case you want it repeated like this: [1 1 1 1 2 2 2 2 ....] you can use repmat and reshape:

reshape(repmat(A,4,1),[],1)
