How can I find the index of a the characters within a string?

Input_String = 'Hello World';
Num_Letters = numel(Input_String);
Index_Letters = % I used find(Input_String), but it gives me 1:11 as index, when I only need 1:11 without index 6. At index 6, it's a blankspace.%
Num_Blanks = sum(Input_String ==' ');
Index_Blanks = strfind(Input_String,' ');

There are many useful functions to handle string data. Please refer to the related documentation page ( https://jp.mathworks.com/help/matlab/characters-and-strings.html ).

The followings are some example.

Input_String = 'Hello World';

- To find the index of the space (' ')

idx = strfind(Input_String,' ');

- To count the number of space character

num = count(Input_String,' ');

- To replace space with specific character

newString = replace(Input_String,' ','YourString');

- To erase space

newString = erase(Input_String,' ');

...etc
