Running multiple functions simultaneously

Dear all, I calculate a Jacobean matrix numerically by modifying each component of a vector of parameters "V" and see the impact of this change on the solution of my problem. I can do this operation by making the modification component by component of the vector of parameter "V" which has a dimension of (14*1). Problem : I would like to make this calculation, but a simultaneous (i.e. in parallel procedure). Create multiple problems (length(V) = 14), where each contains a variation of a component of my vector B--->This task is easily encoded. The problem is how, I ask Matlab to start for solving these 10 created problems simultaneously. Thank you in advance for each answer.

Do you have the Parallel Computing Toolbox?

If so, this is easily doable with parfor, parfeval or batch.

If not, contact your friendly MathWorks' account manager for a trial.

Dear Sean de Wolski, Firstly, thank-you for your answer, but I have a Matlab 2011b (i.e. the all commands "parfor, parfeval or batch" don't exist. I would only run several matlab functions using a computer of 12 cores. I would to start the run of each function in a specific core. Thank-you in advance for any advice...

With the parallel computing toolbox, batch and parfor exist. parfeval was added later. You do not have the toolbox if these functions aren't present.
