Matlab finds the index function used to remit a vector containing the linear indices of each nonzero element in the array. For Matlab find the index “Find” statement is used. For example, D = find(Y) remits a vector containing the linear indices of each nonzero element in array Y. If...

% Format files. To see a list of supported formats, with their file % extensions, use the IMFORMATS function. If IMREAD cannot find a file % named FILENAME, it looks for a file named FILENAME.FMT. % % The return value A is an array containing the image data. If the file ...
A single index value can be used to reference vector elements. For example >> x = v(3) returns the third element of vector v when v is either a row or column vector. Using a single index value, create a variable named p containing the 6th element in the vector density. ...
