Question

IN MATLAB

Write a function count_substr which takes a string and sub-string as an input and gives the number of occurences of the sub-string as output

You will have to refer to the documentation of strfind

Opens in new tab

or count

Opens in new tab

and implement this (Should be straight forward if you understand how it works)

x = "HiHiiHiiiiiii";

y = "Hi";

ct = count_substr(x,y) %use this as your function header

"Hi" occurs three times, so count should be be 3

PS: You can write this function definition in a single line of code

If you are adventurous, try to write this function definition from scratch!

CODE TO CALL YOUR FUNCTION:

x = "HiHiiHiiiiiii";

y = "Hi";

ct = count_substr(x,y)

Answer 1

%   MATLAB program to count the occurences of a substring in a string

function ct = count_substr(x,y)
    ct = count(x,y);
end

Note: The solution is written in single line, for queries drop me a comment.
