Implementation of Modelica.Blocks.Tables.CombiTable2D Interpolation outside interval is wrong

[Jens Frenkel]

MSL:
Table look-up in two dimensions (matrix/file)

If the input signal u1 or u2 is outside of the defined interval, the corresponding value is also determined by linear interpolation through the last or first two points of the table

Implementation:

/* if out of boundary, just set to min/max */
x1 = fmin(fmax(x1,InterpolationTable2D_getElt(table,1,0)),InterpolationTable2D_getElt(table,table->rows-1,0));
x2 = fmin(fmax(x2,InterpolationTable2D_getElt(table,0,1)),InterpolationTable2D_getElt(table,0,table->cols-1));
