contour(matrix) |
| See Also | mlmode_contour , surface, mesh , and contour(matrix, levels) |
contour uses the default settings for the arguments
levels
,
x
,
y
,
z
, and
option
.
The number of contour levels is equal to the number of colors in
the current color sequence as returned by gcolor
and the levels are evenly spaced between the minimum and maximum
value in matrix.
The x-axis corresponds to the row index of matrix,
and the y-axis corresponds to the column index of matrix.
The contour plane corresponds to z = 0,
and the contour does not hide lines behind it.
contour
to plot z = x y, where both x and y
range from 1 to 8, by entering
x = seq(8)
y = x'
matrix = x * y
format int "3"
write("screen", matrix)
O-Matrix will respond
1 2 3 4 5 6 7 8
2 4 6 8 10 12 14 16
3 6 9 12 15 18 21 24
4 8 12 16 20 24 28 32
5 10 15 20 25 30 35 40
6 12 18 24 30 36 42 48
7 14 21 28 35 42 49 56
8 16 24 32 40 48 56 64
The first line above corresponds to x = 1
and the last line corresponds to x = 8.
If you continue the previous example by entering
contour(matrix)
O-Matrix will generate the following plot.
