When you redefine ORIGIN in a worksheet, keep in mind the following suggestions: Note that when you try to refer to V Mathcad displays an appropriate error message. Figure 10-6 shows a worksheet with the ORIGIN set to 1. If you change ORIGIN to one, Mathcad no longer maintains an element zero for vectors or a zeroth row and column for matrices. For example, to change the ORIGIN to one, type: ORIGIN-1. Enter a global definition for ORIGIN anywhere in your worksheet.Choose the Options command from the Math menu, click on the Built-In Variables tab, and change the value of ORIGIN.There are two ways to change the value of ORIGIN for the whole worksheet: When you use subscripts to refer to array elements, Mathcad assumes the arrays begin at the current value of ORIGINįor example, suppose you want all your arrays to begin with element one. To change this, change the value of the built-in variable ORIGIN. This is shown on the right-hand side of Figure 10-5īy default, Mathcad arrays begin at element zero. You can also extract a single row from a matrix by extracting a column from the transposed matrix.
