On Input N is the order of the matrix. D contains the diagonal elements of the input matrix. E2 contains the squares of the subdiagonal elements of the input matrix in its last N-1 positions. E2(1) is arbitrary. On Output D contains the eigenvalues in ascending order. If an error exit is made, the eigenvalues are correct and ordered for indices 1,2,...IERR-1, but may not be the smallest eigenvalues. E2 has been destroyed. IERR is set to Zero for normal return, J if the J-th eigenvalue has not be... |

Tcl/trace(3) -- Monitor variable accesses
|
|
This command causes Tcl commands to be executed whenever certain operations are invoked. At present, only variable tracing is implemented. The legal option's (which may be abbreviated) are: trace variable name ops command Arrange for command to be executed whenever variable name is accessed in one of the ways given by ops. Name may refer to a normal variable, an element of an array, or to an array as a whole (i.e. name may be just the name of an array, with no parenthesized index). If name refe... |

Tcl_Interp *interp (in) Interpreter containing variable. char *varName (in) Name of variable. May refer to a scalar variable, to an array variable with no index, or to an array variable with a parenthesized index. If | the name references an | element of an array, then | it must be in writable | memory: Tcl will make | temporary modifications to | it while looking up the | name. int flags (in) OR-ed combination of the values TCL_TRACE_READS, TCL_TRACE_WRITES, and TCL_TRACE_UNSETS, and TCL_GLOBAL... |
