How to make a 1D become 2D and create a contourf plot

11 views (last 30 days)
Let say:
time=[1:10];
height=[100:100:1000];
temp=[273:1:282];
So as, i can plot(time,temp)
and i can also plot(temp,height)
How can I make newTemp(time,height) so that I can make a contourf plot such that
v-[1:1:100]
contourf(time,height,newTemp,v)

Do you have any equations for that? What is the dependency?

There is no equation to this problem. I want Temp(time,height) for my contourf plot.

You could use meshgrid which returns the 2-D grid coordinates contained in the vectors time and height.
[timeX,heightY] = meshgrid(time, height);
Then You can define newTemp for all the values of [timeX,heightY] and use contourf.
v-[1:1:100]
contourf(timeX,heightY,newTemp,v);
Refer here for more information about meshgrid.
Refer the section Contours at Ten Levels in following example for usage of contourf.
