Description
This block is used to create a string which can be used to store text data. Strings behave differently from other native simulink data types in that they are always accessed by reference. This means that only one copy of the data exists. This means that if a string handle is run to two blocks and the first block modifies the string, the second block will see the modified string even if it is not connected to the output of the first block. This is due to the large memory requirement of most strings. The size of the string must be set before compiling. The size of the string represents the largest amount of data that it can hold. A string can have less data in it than its size. It is best to set the size to the longest string that will be stored. Setting the size significantly higher can lead to high memory use.
