: Returns the row and column subscripts for nonzero elements, which is especially useful for 2D matrices.
The MATLAB find function locates the indices and values of nonzero elements in an array or identifies elements that meet specific logical criteria. While it is a foundational tool for data filtering, MATLAB often recommends using instead for better performance in simple scenarios. Basic Syntax and Return Values matlab find function
The function's output depends on how many arguments you request: : Returns the row and column subscripts for
: Returns row and column indices plus a vector v containing the actual nonzero values . Basic Syntax and Return Values The function's output
: Finds only the first or last n occurrences. The direction can be 'first' (default) or 'last' . Common Use Cases
You can find elements that meet complex conditions by using relational operators like == , > , or < inside the function. find - Find indices and values of nonzero elements - MATLAB
: Returns a vector of linear indices for all nonzero elements in X .
