In the Matrix Catalog, the size of a matrix is shown beside the matrix name. (An empty matrix is shown as
1*1.) The number of elements in it is shown beside a vector.
You can also create and store matrices—named or unnamed—in Home view. For example, the command:
POLYROOT([1,0,–1,0])►M1
stores the roots of the complex vector of length 3 into the variable M1. M1 will thus contain the three roots
of : 0, 1 and –1.
