vlookup returns a vector, so use indexing to get at the value and then assign that to S as required.

Replace NaN with 0 in the above example; uses the programming construct "on error" to trap the vlookup no-match error.

Perhaps my problem is still there.... As I am trying to use VLOOKUP for not a single variable but for a range of variables..

Can you suggest how can I solve the following problem.... I have reaction matrix...at the restraint nodes..in order to calculate shear force and generalire the calculation for shear force.. I need a matrix S..which gives a value of zero at the unrestrained nodes....

Of course, there's usually more than one way to skin a cat in Mathcad ...

Hey..is there any way... I can convert this matrix (1 x 1) to scalar... it would solve my problem...

??  See the above ... that's what the array index does (the small subscript 1 at the end of the vlookup expression).
