static const char* Hxi::mx_count_columns ( const char *  row, int &  n  )

static

Count numbers of columns n of argument row.

Return a pointer to the first non-whitespace character behind the row. Note: Comma ',' or whitespaces are valid column delimiters.

References mx_forward_argument(), and mx_forward_whitespaces().

Referenced by mx_count_dimensions().

static const char* Hxi::mx_count_dimensions ( const char *  arg, int &  m, int &  n  )

static

Count numbers of rows m and columns n of argument arg.

Return a pointer to the first non-whitespace character behind the argument. Note: Brackets '[' and ']' are array delimiters. Semicolon ';' is required as row delimiter.

References mx_count_columns(), and mx_forward_whitespaces().

static const char* Hxi::mx_forward_whitespaces ( const char *  start )

static

Return a pointer to the first non-whitespace character at or behind start.

Note: newline '
' is considered as an ordinary whitespace character, i.e. a semicolon ';' is required to delimit rows of a matrix.

Referenced by mx_count_columns(), mx_count_dimensions(), mx_forward_argument(), and mx_parse_argument().

static void Hxi::mx_foutput ( FILE *  fp, mxArray *  mx_arg  )

static

Print mxArray to FILE.

References mxFree().

static mxArray* Hxi::mx_parse_argument ( SimStruct *  S, const char *  arg  )

static

Parse one argument and return a dynamically allocated mxArray.

The function recognizes

• strings delimited by '\'' or '"'
• scalar doubles
• matrices of doubles
• cell arrays enclosed by '{' '}' are parsed as strings
