Users wanting compatible code for non-integer To be consistent withĭec2hex and dec2base, Octave produces an error for non-integer Of fix ( d) for positive values, but, as of R2020b and inĬonflict with published documentation, appears to use ![]() Non-integer values for d, truncating the value using the equivalent Known MATLAB Incompatibility: MATLAB’s dec2bin allows Programming Notes: The largest negative value that can be converted into : x = str2num ( s) ¶ : = str2num ( s) ¶Ĭonvert the string (or character array) s to a number (or an array). Str2double can replace str2num, and it avoids the security Note that numeric elements in a mixed string/numericĬell array are not strings and the conversion will fail for these elements Str2double returns a NaN for any element of s for whichĬonversion fails. NaN for any row of s that could not be converted. Similarly, for character array input str2double returns a For cell arrays each character stringĮlement is processed and a double or complex array of the same dimensions asįor unconvertible scalar or character string input str2double returnsĪ NaN. ForĬharacter arrays the conversion is repeated for every row, and a double orĬomplex array is returned. S may be a character string, character matrix, or cell array. The special input values Inf, NaN, and NA The brackets indicate optional arguments and 'd' indicates zero or If present, a and/or b are of the form ddd] where Numbers and the complex unit is 'i' or 'j': The string must be in one of the following formats where a and b are real Only the real partĬonvert a string to a real or complex number. Non-integers are rounded to integers before display. Results, use sprintf (see Formatted Output). This is in contrast to MATLAB which tampers with theĬonvert an integer (or array of integers) to a string (or a character Otherwise, results will beĪny optional format specified by the programmer is used without Integers larger than flintmax may not be displayed correctly.įor complex x, the format string may only contain one outputĬonversion specification and nothing else. Over the results, use sprintf (see Formatted Output).įor MATLAB compatibility, leading spaces are stripped before returning ![]() The num2str function is not very flexible. Included in the string in such a way that eval will result in theĬonstruction of a matrix of the same class. If the argument "class" is given then the class of x is Part and n(2) defines the precision of the imaginary part. Otherwise n(1) defines the precision of the real Then both real and imaginary parts of the matrix are printed to the same The precision of the values is given by n. The returned string may be used to reconstruct the original matrix by using : s = mat2str ( x, n) ¶ : s = mat2str ( x, n, "class") ¶įormat real, complex, and logical matrices as strings.
