A function to calculate the cost of the objective function

1	cost(W,init_list,lambda=0.2)

`W`	The matrix to be factorized
`init_list`	A list containing the updated results in this iteration
`lambda`	A parameter to set the relative weight of the sparsity constraint

A number indicating the total cost of the objective function
