.. _auto_matrix_createfromvectorasrow:

*CREATE A MATRIX USING THE VECTORS*
===================================

Assembles a matrix by stacking up to three numeric lists as rows. Each supplied vector becomes one row of the output matrix; omitted vectors are skipped. Use this worker whenever you need to construct a 1×N, 2×N, or 3×N matrix from individual list-typed outputs of upstream workers.

     - Description
   * - Vector 1
     - vector1
     - list
     - —
     - 
     - Numeric list that will occupy row 1 of the output matrix; optional — omit if fewer than one row is needed.
   * - Vector 2
     - vector2
     - list
     - —
     - 
     - Numeric list that will occupy row 2 of the output matrix; optional — omit to produce a single-row matrix.
   * - Vector 3
     - vector3
     - list
     - —
     - 
     - Numeric list that will occupy row 3 of the output matrix; optional — omit to produce a one- or two-row matrix.
