Type: | Command | ||||
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 | ||||

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, !Îor PSOLVER or !ÖDIFF | ||||
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. | ||||
