Algorithm (Workflow)
This function, strarr2char, is designed to convert a single row or single column string array into a character chain. It is part of the SolidGeometry library and was introduced in version 5.4. The function is authored by Tim Lueth and is part of the VLFL-Lib, dated December 13, 2023.
Input Parameters
- strarr: A string array that can be either a single row or a single column.
- varargin: Optional parameters, where the first optional parameter is expected to be a separator.
Output Results
- chr: A character chain that contains the elements of the string array, formatted according to the specified separator.
Algorithm Steps
- The function begins by determining the separator to use. It calls
getfuncparams with the first optional parameter from varargin, defaulting to a double quote (") if no separator is provided.
- A
switch statement is used to handle different separator cases:
- Case '"': If the separator is a double quote, the function joins the elements of
strarr with " " (a space enclosed in double quotes) and formats them into a character string with each element enclosed in double quotes.
- Case ',': If the separator is a comma, the function joins the elements of
strarr with a comma followed by a space (", ") and formats them into a character string.
- Otherwise: If an unknown separator is provided, the function throws an error indicating the unknown separator.
Example Usage
Consider the following example:
x = [ "START" "move a from b to table" "move b from c to a" "move c from table to b" "FINISH" ];
y = strarr2char(x);
u = char2strarr(y);
In this example, x is a string array. The function strarr2char converts it into a character chain y, and then char2strarr can be used to convert it back to a string array u.
