Plot A Matrix

Is it possible to plot a matrix? i have a matrix 7x7 with valure around 1 and i want to show (maybe with different colour) how near are to 1 these value as it is a temperature or something like that.

Answer 1

[Walter Roberson]

imagesc() would probably be better than surf() for this purpose.

imagesc(magic(7))

[Salvatore Turino]

yes this is what i was looking for.

thank you

Answer 2

[Sean de Wolski]

maybe one of these?

doc mesh
doc surf
doc contour

[Salvatore Turino]

mmm can you give me an example?

>> surf(magic(5))

magic(5) creates a 5x5 magic square, surf plots it as a surface. The more specific you can be with the results you're after, the better we can tune our answers.
