Identifies local maxima and minima in a gridded function.
Value
List containing:
- maxima
Matrix of (i,j) coordinates for local maxima
- minima
Matrix of (i,j) coordinates for local minima
Examples
if (FALSE) { # \dontrun{
grid <- create.grid(50)
f <- function(x, y) sin(3*x) * cos(3*y)
f.grid <- evaluate.function.on.grid(f, grid)
critical <- find.critical.points(f.grid)
print(critical)
} # }
