Algorithm (Workflow)

This function, char2strarr, is designed to convert a character chain containing strings separated by a specified delimiter into a string array. It is part of the SolidGeometry library, version 5.4, and was introduced by Tim Lueth in December 2023.

Input Parameters

• chr: A character chain where strings are separated by a delimiter, typically a quotation mark.
• splt: An optional parameter specifying the delimiter character. The default delimiter is a quotation mark ('"').

Output

• strarr: A string array containing the separated strings from the input character chain.

Algorithm Steps

1. The function begins by determining the delimiter using the getfuncparams function. If no delimiter is provided, it defaults to a quotation mark ('"').
2. The split function is used to divide the input character chain chr into parts based on the specified delimiter splt.
3. The strtrim function is applied to remove any leading or trailing whitespace from each of the split strings.
4. Empty strings are removed from the array using strarr(~ismember(strarr,'')).
5. The resulting array is converted into a string array and transposed to ensure it is in the correct format.

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 = char2strarr(x);

This will convert the character chain x into a string array y with each quoted segment as an element.

Another example with a different delimiter:

x = 'space on $A, space on $B, $A on $B';
char2strarr(x, ',');

Here, the delimiter is a comma, and the function will split the string accordingly.
