Linear equation number

| Vector | C |
в палитре на схеме

The block is used together with the blocks Coefficients of the linear equation and SLE results. The block is a counter for the number of equations in a system with a given name. This block returns the vector of unique numbers of SLE rows (equations). When initializing the schematic the common for the schematic SLE solver with the unique name <solvername> is initialized that includes the counter of number of equations. In this case it is possible either matching of the given system with the main Jackobian that is used for implicit methods of integration, or the presence of an another system of linear equations. This block, when initializing the schematic <equcount>, adds to this counter the number of equations specified in the properties of the block and at the output forms a vector of equation numbers with dimension <equcount>. The outputs of this block is not changing during calculation.

Свойства

  • Name of the SLE solver is the name of the solver (row <solvername>) that processes (solves) the SLE. It should be the same for all the blocks "Linear equation number", "Coefficients of the linear equation" and "SLE results" belonging to the same system.
  • Number of equations is a natural number <equcount>, i.e. the number of equations added by this block to the system <solvername>.
