% A = IMREAD(FILENAME,FMT) reads a grayscale or color image from the file % specified by the string FILENAME. If the file is not in the current % directory, or in a directory on the MATLAB path, specify the full % pathname. % % The text string FMT specifies the format of the f...
to MATLAB's double representation. The string may contain digits, a comma (thousands separator), a decimal point, a leading + or - sign, an 'e' preceding a power of 10 scale factor, and an 'i' for a complex unit. If the string S does not represent a valid scalar value, STR2DOUBLE...
54、. v =11 Recall that when you use find on a logical expression, the output vector v does not contain the nonzero entries of the input array. Instead, it contains the nonzero values returned after evaluating the logical expression. Example 5 Some operations on a vector x = 11 0 33 ...
In addition the format may contain literal character strings; these will be skipped during reading. If the input string does not match this literal, the processing terminates. Parsed words corresponding to the first specifier are returned in the first output argument and likewise for the rest of ...
String arrays can contain both empty and missing values. An empty string contains zero characters. When you display an empty string, the result is a pair of double quotes with nothing between them (""). The missing string is the string equivalent toNaNfor numeric arrays. It indicates where ...
