Else, we check to see if the first character is. If we read a -1, this means we have reached the end of the file, so get out of the loop. Now, until we reach the end of the file, get one line of text starting from the top of the file and we proceed to the end. Next, we declare an empty cell array called nums which will store our numbers that you are getting when parsing your text file. We check to see if the ID returned from fopen is -1 and if that's the case, we couldn't find or open the file so spit out an error. We first use fopen to open up the file for reading. Let's assume your text file is stored in text.txt: fid = fopen('text.txt') Because you will probably have each line containing a different amount of numbers, let's store each array into a cell array where each element in this cell array will contain the numbers per line. You will receive a cell array of strings, so you'd have to convert this into an array of numbers. With each line, you check to see if the first character is a semi-colon and if it is, split up the string by the delimiter from the second character of the line up until the end.

We can also create multiple string arrays and manipulate them according to the business requirements. Different data types like character, numeric, and date can be converted into string datatype in Matlab. It provides many functions that can be used to manipulate the strings in an array. String arrays and its functionalities have been introduced in Matlab in its recent version. To concatenate both strings into one string array, we can use the вЂњ+вЂќ operator. To access the first element of the first row we can use: This above function displays all the elements of the second row.

To add and rearrange the strings in an array we can use plus operator to add strings, join, split, sort functions to rearrange the strings. The index number starts from zero in an array. The elements in an array can be accessed by using an index number.

How to access the elements of String Array?

To convert the string array into a numeric array, we use a double function in Matlab. We can also convert a numeric array into string array: To find the number of characters in a string, we use strlength () function: Please find the below examples: Example #2Д¬ is a character vector and it can be converted into a string by using string function. We can convert character, numeric array to string array by using the вЂњstringвЂќ function. We can also find the unique words in the array by using a unique function. This function splits the array whenever there is space and it results in a 6* 1 string array. Split function breaks the string whenever there is space between the string and consider it as a single word. Next, to split the string, we use the split function. This following string contains only lowercase letters. To convert the string into lowercase characters we can use the lower function. To eliminate the special character between the strings we can use erase function which will eliminate вЂњ!вЂќ symbol from the string.ДЄr = 'Jack and Jenny !pursued !pursued!Engineering' Please find the below list of functions with examples: Example #1ДЄr = вЂњJack and Jenny !pursued !pursued!EngineeringвЂќ There are many functions that can be performed using a string array. Examples to Implement String Array in Matlab St = string (D, format): This is used to convert the input of date data type to string data type as specified in the format of the date.
