MuPAD® notebook has two types of regions for entering data:
Text regions serve for entering your comments. They can contain text, tables, mathematical formulas, and graphics. Text regions do not have not bracket markers. The default font color for text regions is black. To start a new text region, click outside the gray brackets and start typing. Alternatively, you can insert a new text region by selecting Insert>Text Paragraph or Insert>Text Paragraph Above. You cannot insert a text region inside a region of other type or between adjacent input and output regions.
Input regions serve for entering your code. They can contain MuPAD mathematical expressions and commands in the MuPAD language. Input regions have gray bracket markers. The default font color for input regions is red. When you evaluate an expression in the bottom input region, MuPAD inserts a new input region below. To insert new input regions in other parts of a notebook, select Insert>Calculation or Insert>Calculation Above from the main menu. Alternatively, use the Insert Calculation button .
MuPAD notebook has a special type of region for viewing results:
Output regions serve for viewing results. These regions automatically appear when you evaluate input regions. The results can include graphics and error messages. The default font color for output regions is blue. You cannot edit data in the output regions. To change the results, edit the associated input region and evaluate it by pressing Enter. Also, you can copy results from the output regions to the text and input regions. When you copy outputs to the input regions, MuPAD inserts ASCII equivalents of the results in the input regions.
