How to plot cell array data?

I'm trying to plot the contents of a cell array (RSD_c{v}) composed of 5 32x3 double matrices. I want each column to be the X,Y,and Z variable, respectively.

if true
  %Plot bias vs. B vs. v
  %bias, B, and v contained in RSD_c(:,1), RSD_c(:,2), and RSD_c(:,5), respectively
   figure;hold on;
   cellfun(@scatter3,RSD_c(:,1),RSD_c(:,2),RSD_c(:,3));
end

When I run the above code,I get the error, "??? Error using ==> scatter3 at 63 X, Y and Z must be vectors of the same length."

What am I doing wrong? How do I fix this?

[Adam]

cellfun( @(x) scatter3( x(:,1), x(:,2), x(:,3) ), RSD_c )

should work, though I haven't double-checked the syntax in Matlab itself.

doc cellfun

should give examples of this syntax for calling.

Thanks. I used the following code:

if true
  figure;hold on;
cellfun( @(x) scatter3( x(:,3), x(:,4), x(:,5) ), RSD_c );
title('Relationship Between Relative Standard Deviation, Bootstrap Replicates, and Dimension')
xlabel('Bootstrap Replicates') % x-axis label
ylabel('Relative Standard Deviation') % y-axis label
zlabel('Dimensions') % z-axis label
end

It does create a plot, and tracing the points shows that they have x, y, and z coordinates. However, the graph is 2-dimensional, with the points color-coded by z-coordinate.

Does anybody know how to fix this?
