This is used to read numerical or other types out of a string according to the provided format string. The format string is a standard C format string. A format string can contain both text to be matched and format specifiers which are used to read data from the string. The output ports for this block will be created based on the format string entered in the parameter. To match a % to the string use %%.
A format specifiers has the following form %[*][width][length]specifier
Note: Simulink String blocks are not compatible with Raptor blocks. Please use Raptor String blocks.
*
Description
*
Specifies that the data read by this specifier should be discarded
width
Description
(number)
The maximum number of characters to be read.
The length field modifies the default data type of the incoming port for a specifier.
