Question

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 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!

Please use matlab

the output should be the count value

Answer 1

Save the following function code in a file named count_substr.m

function c = count_substr(x,y)
   c = length(strfind(x,y));
end

================
Now in command window or another script file, you can call the function using the following lines and execute
x = "HiHiiHiiiiiii";
y = "Hi";
ct = count_substr(x,y)
