Algorithm (Workflow)
This function, sprintfvec, is designed to format and print vectors in a way that can be used for code generation. It is part of the SolidGeometry library and was introduced in version 4.9.
Input Parameters
- f: A file pointer, default is an empty string ('').
- s: A format string, default is '%d'.
- X: A numeric matrix or vector.
Output Results
- ostr: The formatted output string.
- nstr: A secondary formatted string used internally.
Algorithm Steps
- Retrieve input parameters using
getfuncparams function. If only one argument is provided and it is numeric, assign it to X and set s to '%d'. If f is a character, swap s and X.
- Define format strings
sfmt1, sfmt2, and sfmt3 using the provided format string s and a separator character sepchar.
- Initialize
ostr with '[ ' and nstr as an empty string.
- Iterate over each element of the matrix
X using nested loops. For each element, append the formatted string to ostr and nstr.
- Remove the last separator from
ostr and close the bracket with ']' to complete the formatted string.
Example Usage
Examples of how to use the function:
sprintfvec('%.3f',[1 2 3; 4 5 6])sprintfvec('%d',[1 2 3; 4 5 6])
