how to solve 'ones error' in my code below

Error using ones

Size inputs must be integers.

Error in matlab.internal.builtinhelper.repmat (line 59)

B = A(ones(siz,'int8'));

Error in inspect_rtmri (line 1097)

vid_rs = repmat(struct('cdata', [], 'colormap', []), 1, nf);

##### here is the code####

if nargin <= 2

M = varargin{1};

checkSizesType(M);

if isscalar(M)

siz = [M M];

elseif ~isempty(M) && isrow(M)

siz = M;

else

error(message('MATLAB:repmat:invalidReplications'));

end

siz = double(full(siz));

else % nargin > 2

siz = zeros(1,nargin-1);

for idx = 1:nargin-1

arg = varargin{idx};

if isscalar(arg)

siz(idx) = double(full(checkSizesType(arg)));

else

error(message('MATLAB:repmat:invalidReplications'));

end

end

end

if isscalar(A) && ~isobject(A)

B = A(ones(siz,'int8')); ###### the error comes from here

elseif ismatrix(A) && numel(siz) == 2

[m,n] = size(A);

nf should be an integer.
