How to use str2double( ) In MATLAB
The str2double() function is used for the conversion of strings to double-precision values.
Syntax:
str2double(string)
Here, str2double(string) is used to convert the text in the specified string to double-precision values.
Example:
Matlab
% MATLAB code for regexp() demonstration % Initializing a cell array A = {'gfg'; 'gfg1.23GFG'; '5gfg10'}; % Calling the regexp() function over the % above cell array to extract number part B = regexp(A,'\d+(\.)?(\d+)?','match'); % Calling the str2double() function to % convert the text to double-precision values out = str2double([B{:}]) |
Output:
out = 1.2300 5.0000 10.0000
