where the actual array bounds are transmitted at run time. An array that is local to a procedure may be specified as an automatic array whose bounds depend on another argument, as in Sign in to download full-size image to define an array work whose size depends on that of another array...
-Dname Define name to be 1 On the command line, this option will define name as if: #define name[=def] had appears in the source file. If no =def specified, the name name is defined as the value 1. The macro symbol name is passed on to the preprocessor fpp (or cpp -- see ...
On the command line, this option will define name as if: #define name[=def] had appears in the source file. If no =def specified, the name name is defined as the value 1. The macro symbol name is passed on to the preprocessor fpp (or cpp -- see the -xpp option) for expansion...
-compatibleArrayDims Build a MEX-file using the MATLAB Version 7.2 array-handling API, which limits arrays to 2^31-1 elements. -D<name> Define a symbol name to the C preprocessor. Equivalent to a "#define <name>" directive in the source. Do not add a space after this switch. -D<...

EXPLANATION: Break exception generated a SIGTRAP signal (described in signal(3)). Core dump file created. The cause is an array subscript that is outside the dimensioned boundaries of that array. Try recompiling using the -check bounds option (perhaps with the f77_dump_flag environment variable...
Intel(R) Compiler includes compiler options that optimize for instruction sets that are available in both Intel(R) and non-Intel microprocessors, but may perform additional optimizations for Intel microprocessors than for non-Intel microprocessors. In addition, certain compiler options for Intel(R) Com...
