[EDIT: 20110621 11:03 CDT - merge duplicate - WDR]

hallo,

i have an m*n cell matrix that contains a x*4 matrix in each cell.

i want to draw a surface plot, a contourf to be precise, in which the color value is the number of the rows of which are composed the matrixes in the cells,according to the value of the y and z coordinates, that are unique for each cell in thee big m*n cell matrix. the y and z coordinates are written in the 2nd and 3d column of each x*4 matrix (in easy terms, a map of the x value all around the cell matrix acording to the y and z of the cells )

hope that somebody can help me, and hope that the message was clear enough.

thanks in advance.

Sam

[Material from duplicate question]

hallo,

i have an m*n cell matrix that contains a x*4 matrix in each cell.

i want to create a 2d color surface in which the color value is the number of the rows of which are composed the matrixes in the cells,according to the value of the y and z coordinates, that are unique for each cell in thee big m*n cell matrix. the y and z coordinates are written in the 2nd and 3d column of each x*4 matrix (in easy terms, a map of the x value all around the cell matrix acording to the y and z of the cells )

So if in the 1st cell I have a matrix with 3 rows, I want that on the map a certain color is shown and if in another cell I have a matrix with 54 rows I want another color on the map. the map will be an y z planar surface according to the values of the 2nd and 3rd column of the x*4 matrix contained in each cell.

thanks

To clarify: you want to go into the m*n cell matrix; "the number of the rows" is equal to the x value in each x*4 matrix; and you want to plot unique (x,y,z) sets? Or just unique x values regardless of y and z?

Actually I want to plot a planar surface that shows me, in the correct y and z position how many rows I have in each cell of the m*n matrix, witha color map. SO if in the 1st cell I have a matrix with 3 rows, I want that on the map there is a color and if in another cell I have a matrix with 54 rows I want another color on the map. the map will be an y z planar surface according to the values of the 2nd and 3rd column of the x*4 matrix contained in each cell.

hope that is more clear now

thanks
