Description:

From a program with two arguments, builds a matrix with the specified number of rows and

 

columns, with aij = f(i,j).

Access:

Catalog, …µ

Input:

Level 3/Argument 1: The number of rows you want in the resulting matrix.

 

Level 2/Argument 2: The number of columns you want in the resulting matrix.

 

Level 1/Argument 3: A program that uses two arguments. An expression with the two variables I,

 

J can be used instead.

Output:

The resulting matrix.

Flags:

Exact mode must be set (flag –105 clear).

 

Numeric mode must not be set (flag –3 clear).

Type:

Command

Description:

Solves a linear differential equation with constant coefficients, or a system of first order linear

 

differential equations with constant coefficients.

Access:

Symbolic solve, or PSOLVER or DIFF

Input:

Level 2/Argument 1: For a single equation, the function forming the right hand side of the

 

equation. For a system of equations, an array comprising the terms not containing the dependent

 

variables.

 

Level 1/Argument 2: For one equation, the auxiliary polynomial. For a system of equations, the

 

matrix of coefficients of the dependent variables.

Output:

The solution.

Flags:

Exact mode must be set (flag –105 clear).

 

Numeric mode must not be set (flag –3 clear).

 

Radians mode must be set (flag –17 set).
