Meshgrid compatible streamline data transformation for vector data?

I have an array of vector data called fieldvalue(x,y,z,v) where x,y,z are spatial coordinates from 1 to 321 and v ranges from 1 to 3, holding vector data.
For example,
fieldvalue(1,1,1,1) is the value along I_hat for coordinates 1,1,1 fieldvalue(1,1,1,2) is the value along J_hat for coordinates 1,1,1 fieldvalue(1,1,1,3) is the value along K_hat for coordinates 1,1,1
Thus the vector field triplet values for location 1,1,1 is [fieldvalue(1,1,1,1),fieldvalue(1,1,1,2),fieldvalue(1,1,1,3)]
Silly question, how do I format this data for plotting streamlines?
I keep getting an non-meshgrid compatible error message no matter how I pull the vector data from my array.
Is there an easy way for me to convert my array vector data to something matlab likes?
