Browse Matrix: Viewing Arrays, Matrices, or Vectors
Use the Browse Matrix dialog to view large 1-D or 2-D Arrays, Matrices, or Vectors, or to display cross-sectional views of large multi-dimensional Arrays.
By default, large Arrays, Vectors, Matrices, or higher dimensional rtables are displayed using a summary format. For example,
The contents of these objects can be viewed by using the Browse Matrix tool.
To launch the Browse Matrix dialog, double-click the object, that is, the summary format.
The Browse Matrix dialog has three tabs: Table, Image, and Options.
Inserting the Image into the Worksheet
Exporting Data to Excel(R)
Setting the Maximum Dimension for Inline Display of Arrays, Matrices, and Vectors
The default view for these objects is a spreadsheet representation. To edit table entries, double-click a cell. One dimensional tables are displayed as a single column, independent of whether the underlying object is a row or column vector.
Arrays that are two or higher dimensions can be displayed as an image.
The default zoom setting is Scale to fit. Zoom factors of 1 to 4 times can be selected.
Two styles of display are possible: Magnitude or Structure. The Magnitude display option sets image color in each pixel based on the relative magnitude of the element in the corresponding array position. The Structure display option indicates zero versus nonzero elements. With either view, a coarse image is displayed initially for large matrices. The coarse view is later refined to show more detail.
The following color scales are available:
Grayscale - black and white
Hue - red, orange, yellow, green, cyan, blue, magenta
Hot - black, red, orange, yellow, white
Cool - white, cyan, blue, black
For multi-dimensional Arrays, you can change the view so that different dimensions are assigned to the horizontal and vertical axes.
An Options tab is selectable for two-dimensional and higher Arrays. By default, the first dimension is displayed vertically and the second dimension is displayed horizontally. All other dimensions have a fixed value, which is initialized to the minimum value for the dimension. To assign dimensions, select the Row or Column check box.
For 2-D Arrays, the Fixed column is not displayed. To change the value of a fixed dimension for a multi-dimensional Array, enter the value in the Fixed column.
To insert the image view into the worksheet, click the Insert button. The image is inserted after the execution group containing the array.
You can export data from Maple to an Excel spreadsheet.
Click the Export button in the Browse Matrix. The Export to Excel dialog opens.
Select the spreadsheet to which to export data by clicking the Browse button.
Select the Sheet Name: Sheet 1, 2, or 3.
(Optional) Enter the spreadsheet cell into which to enter the data. By default, the data is loaded starting in cell A1.
Click OK. The dialog closes. Click Done to close the Browse Matrix.
By default, rtables (such as Arrays, Matrices, and Vectors) that have dimensions of 10 or less are displayed inline. To change this setting, use the interface command to set the rtablesize variable. For example, interface(rtablesize=15) changes the maximum dimension displayed inline to 15. See interface for more information.
Note: In the Command-Line version, the default is 25.
