Is it possible to return a Matrix from a single Set in Matlab?

Hi, I recently wrote a code that looks like this:

function DataSet = Project(SetA, SetB, SetC)
    DataSet = find(SetA, SetB, SetC);

      function DataSet = find(SetA, SetB, SetC)
          Data1 = SetA - SetB;
          Data2 = SetB - SetC;
          Data3 = SetC - SetA;
          DataSet = [Data1, Data2, Data3];
      end
  end

The output looks like this when I input in the command:

DataSet = find(1,2,3)
DataSet = -1

If I insert 3 variables such as [Data1, Data2, Data3] = find(1,2,3)

I would get

Data1 = -1
Data2 = -1
Data3 = -2

which is correct. Is it possible, if so how could I change the code so that it output DataSet as a Matrix instead of just 1 value, because if there's suppose 100 variables, I would not want to manually insert 100 variables.

Yikes! Do not name your own routine "find" ! That is going to confuse the heck out of programmers who are going to think of the MATLAB find() call!

The routine "find" that you define is contained within "Project" and is not available from the command line unless you are at a breakpoint within "Project". Instead you would get MATLAB's find() routine.

No, I did not name my routine find, it was an example written here, sorry for the confusion.

[Walter Roberson]

You need to post the real code then, as the code you posted does not act the way you describe.

[Bob]

function [Force, Motion] = setVar(Mass, Acceleration, Radius, time)
     Force = Mass * Acceleration;
     Motion = speedData(Force, time, Radius, Mass)
     function Motion = speedData(Force, time, Radius, Mass)
          Velocity = 2 * Force * time / Mass;
          AngularV = Velocity / Radius
          Motion = [Velocity, AngualarV];
     end
end

[Bob]

What I would want the output is to return Force, and Motion where Motion is the matrix containing velocity and angualarV, but MATLAB is only return force and 1 variable of Motion(Velocity) when I input

[Force, Motion] = setVar(1,1,2,1) The output is just Force and Motion(Velocity), I am missing a Motion(AngualarV) output.

[Walter Roberson]

Your assignment statement to Motion uses AngualarV instead of AngularV

After fixing that, the output is correct on my system.

[Bob]

Yes, I fixed it, its still output the incorrect version:

function [Force, Motion] = setVar(Mass, Acceleration, Radius, time)
     Force = Mass * Acceleration;
     Motion = speedData(Force, time, Radius, Mass)
     function Motion = speedData(Force, time, Radius, Mass)
          Velocity = 2 * Force * time / Mass;
          AngularV = Velocity / Radius
          Motion = [Velocity, AngularV];
     end
end

Oh, I made a mistake in the other section, it works now. Thank you.
