Hi Omer,
- randperm: This function generates a random permutation of integers from 1 to totalElements, ensuring that the selected indices for obstacles are unique.
Here is an example :
function maze = createMaze(m, n)
% Check if the number of obstacles is less than or equal to total matrix elements
if n > m * m
error('Number of obstacles cannot exceed the total number of matrix elements.');
end
% Initialize the m x m matrix with zeros
maze = zeros(m, m);
% Generate n unique random indices for obstacles
totalElements = m * m;
randomIndices = randperm(totalElements, n);
% Convert linear indices to row and column subscripts
[rowIndices, colIndices] = ind2sub([m, m], randomIndices);
% Place obstacles in the matrix
for i = 1:n
maze(rowIndices(i), colIndices(i)) = 1;
end
end
Hope this helps.
