VANDERMONDE
Type: Command
Description: Builds the Vandermonde matrix (also called the alternant matrix) from a list of objects. That is,
for a list of n objects, the command creates an n × n matrix. The i
th
column in the matrix consists
of the list items raised to the power of (i–1). Sometimes the Vandermonde matrix is defined with
the i
th
row containing the items raised to the power of (i–1); to obtain this, transpose the result
with the command TRAN.
Access: Matrices, !Ø

MATRX MAKE
LL
Input: A list of objects. A vector is allowed too.
Output: The corresponding Vandermonde matrix.
Flags: Exact mode must be set (flag –105 clear).
Numeric mode must not be set (flag –3 clear).
Example: Build the row version of the Vandermonde matrix from the following list of objects:
{x, y, z}
Command:
TRAN(VANDERMONDE({x,y,z}))

Type: Command
Description: Variance Command: Calculates the sample variance of the coordinate values in each of the m
columns in the current statistics matrix (ΣDAT).
