The object of my code is to traverse a matrix and remove each row that contains a zero in any of the columns. I keep getting this error: "Index in position 1 exceeds array bounds. Index must not exceed 253."
This is the code:
load('data')
[nRows, nCols] = size(data);
for row = 1:nRows
for col = 1:nCols
if data(row,col) == 0
data(row,:) = [];
[nRows, nCols] = size(data);
end
end
end

load('data') % Assuming 'data' is your matrix
% Find rows with any zero element
rowsWithZero = any(data == 0, 2);
% Remove those rows
data(rowsWithZero, :) = [];
% If needed, you can now work with the modified 'data' matrix.
