Question

Write a function called char_counter that counts the number of a certain character in a text file. The function takes two input arguments, fname, a char vector of the filename and character, the char it counts in the file. The function returns charnum, the number of characters found. If the file is not found or character is not a valid char, the function return -1. As an example, consider the following run. The file "simple.txt" contains a single line: "This file should have exactly three a-s..." charnum = char_counter('simple.txt','a') charnum = 3 You may find it helpful to download the files for testing and dubugging in MATLAB. simple.txtOpens in new tab Frankenstein-by-Shelley.txt please i need MATLAB script(code) for this assignment.

Answer 1

We will be using the inbuilt function "fileread" of Matlab that converts the text file to a character vector. After that for the length of the char vector, we run a loop and count each occurence of the character.

CODE:

x=fileread("filename.txt");

let c be the char whose number of occurrences we wish to find.

n=length(x);

count = 0;

for i=1:n

if(x(i)=='c') count=count+1;

end

end

display(count);
