 LINREG Linear regression

         T = linreg(y,x,lambda,pesos)

 INPUTS
      x: Input  data matrix with vectors by columns (Rx,N)
      y: Output data matrix with vectors by columns (Ry,N)
 lambda: Regularization parameter (default = 0)
  pesos: Pesos asignados a cada elemento (1xN)

 OUTPUTS
      T: Matrix (Ry,Rx)

 Obtains the least squares approximation of a matrix T 
 such that 

      y = T*x
