# problem.btran

Purpose
This subroutine is deprecated and will be removed in a future release. Use problem.BTran instead.
Post-multiplies a (row) vector provided by the user by the inverse of the current basis.
Synopsis
`problem.btran(vec)`
Argument

vec | Array of length problem.attributes.rows containing the values by which the basis inverse is to be multiplied. The transformed values will also be returned in this array.

Example
Get the (unscaled) tableau row z of constraint number irow, assuming that all arrays have been dimensioned.

    y = [0,1,0,0]
    p.btran(y)
    print("btran result:", y)

Further information
If the problem is in a presolved state, btran works with the basis for the presolved problem.
