Details
The simulation of a random percolation map is accomplished in two steps:
Initialization: Setup matrix of size (ncol*nrow)
Map generation: For each cell in the matrix a single uniformly
distributed random number is generated and tested against a probability
prob. If the random number is smaller than prob, the cell is set to
TRUE - if it is higher the cell is set to FALSE.
