Hello,

I try to plot a mesh, but everytime I get an error. I have 3 files (file1,
file2, file3), every of them contains 1 column and n rows of several data.
Now i want to plot the data so that x-axis contains the values of file1, the
y-axis contains the value of file2 and the z-axis contains the values of
file3.

I tried the following:

load file1.txt;
a=file1;

load file2.txt;
b=file2;

load file3.txt;
c=file3;

[X,Y] = meshgrid(a,b);
mesh(X,Y,c);

but an error occurs by function mesh

thanx for help - Tino

Hi Tino ,


          Could u please provide me some information about the files
which u are using i.e file1,file2,file3.
Well file3 i.e the one with the variable c should be a function of a
and b .


For example if i have a=-2:0.2:2 and
b=-2:0.2:2 and u do [X,Y]=meshgrid(a,b) well it will work but when u
do mesh (X,Y,c)
c should be a function of X,Y (should be generally in an equation
form) then ur mesh(X,Y,c) will work .
Otherwise it will give an error ..





Regards
Anshu

Ok, it's a little bit strange. I have 11 results of an simulation. The
parameters are running from 0.5 to 3.5 in steps of 0.3. For each of this
sumulations exists one file with 2 colums and 42 rows. the first columns is
in each file the same - these are numbers from 0 to 120 in steps of 10. Only
the second column differs from file to file. No I want a mesh with the
values og 0.5 to 3.5 on the x-axis, the values from 0 to 120 on the y-axis
and the values from the second row of the files should be the z-axis.

But how to do this?

Thanx - Tino
