How to configure stream3 arrays

I have a set of data and I am trying to understand how the function stream3 needs the data in order to produce an acurate plot. The data I have is in this form

x=[1,2,3]

y=[4,5,6]

z=[7,8,9]

velocity=[1,2,3;4,5,6;7,8,9]

so the first 3 values are the velocity when x=1, y=4, and z ranges from 7 trough 9, the second 3 values are when x=1, y=5 and z ranges from 7 through 9, the third set of values are when x=1, y=6 and z ranges from 7 through 9.

Im sure that this isnt the way the function needs the data so I was wondering if anyone out there know how the function requires the data in order to get an accurate streamline plot. Oh, and just as a sidenote, whoever has the answer, you frakin' ROCK!!!

By first three do you mean first row or first column?

i mean the values in the first row

I don't think this is acceptable data for stream3. stream3 needs a velocity *vector* at each point in space. That is, each point [x, y, z] should correspond to a velocity vector [vx, vy, vz].

As far as I can tell, it appears that for each point [x, y, z] you have a scalar "velocity" value (i.e. [1, 4, 7] -> 1). That doesn't really provide enough information for stream3.

well, what i gave was just an example, i have the velocity components in u, v and w, but they are all in the same format as described above.

Hello Franco,

I see you have asked 8 questions on MATLAB Answers without accepting a best answer for any of them. Would you take a few minutes to go back and resolve the questions to which you received satisfactory answers?

Thanks.
