Algorithm (Workflow)
This function, find2logical, is designed to convert an index list into a logical vector. It is part of the SolidGeometry library and was introduced in version 4.9. The function is authored by Tim C. Lueth and is categorized under auxiliary procedures.
Input Parameters
- ind: This is the index list, which contains the positions that need to be set to true in the logical vector.
- N: This represents the number of elements in the logical row vector. It defines the length of the output logical vector.
Output Results
- l: The output is a logical row vector of length
N. The positions specified in ind are set to true, while all other positions are false.
Algorithm Steps
- Initialize a logical row vector
l of length N with all elements set to false.
- Set the elements of
l at the indices specified in ind to true.
Example Usage
To convert the index list [1 3 5] into a logical vector of length 6, the function call would be:
find2logical([1 3 5], 6)
This would result in the logical vector: [true false true false true false].
Similarly, using a column vector for ind like [1 3 5]' would yield the same result.
