Array/Series Grid

The dimensions of the value node are set in Node Definition | General and can be scalar, 1 dimensional array, or 2 dimensional array. When a value node is an array or series, its data is edited using a tabular grid within Node Definition | Data.

Rows, Columns and Intervals

Use the up/down arrow buttons or type a number into the box to specify the size of the array. A 1-dimensional array has columns if it's a row vector (the default), rows if it's a column vector or intervals if it's a series. A 2-dimensional array has both rows and columns.

Rows, columns and intervals are always indexed starting with zero.

Series interval entry

Check this box to enter a DPL series rather than a 1-dimensional array. A series has one or more intervals, each of which has a single expression that specifies the values for one or more elements.

Create M x 1 column vector

By default, a 1-dimensional array will be defined as a row vector -- that is, a 1-dimensional array with 5 elements will be the same as a 2-dimensional array with 1 row and 5 columns. Check this box to create a column vector. This can be useful when you want the array to override (see Node Definition | Links) a vertical range in a converted spreadsheet.

General Tips about Editing Node Data

You can use the usual copy and paste shortcut keys, e.g., Ctrl+C, Ctrl+V, to copy and paste data or expressions within the tabular grid. You can also select cells in Excel and copy and paste their values to the grid.

You can use the variable and function keys to build expressions for elements in the grid.
