fopen function - file function:
The fopen opens the file for reading. The fscanf then reads each line one double and one character, and put each pair in individual columns in the matrix. The dimensions identify that the matrix has two rows, by though many columns are essential (equivalent to the number of lines in the file). As matrices store the values which are all of similar type, the characters are stored as their ASCII equivalents in the character encoding (example, 'a' is 97). This matrix has been once created; it may be more helpful to separate the rows into vector variables and to convert the second back to characters, that can be completed as shown below:
>> nums = mat(1,:);
>> charcodes = char(mat(2,:))
charcodes =
abaab
Obviously, the results from fopen and fclose must be checked but were absent here for the simplicity.
Mode The mode of a data set is the value which appears most often. The built-in function in a MATLAB for this is known as the mode. >> x = [9 10 10 9 8 7 3 10 9 8 5 10];
Advanced File Input and Output: In that section, we saw how to read the values entered by user using the input as well as the output functions disp and fprintf, that shows inf
Illustration of Indexing: Though, rather than of creating the index vector manually as shown here, the process to initialize the index vector is use to a sort function. The al
Median The median is defined only for a data set which has been sorted first, that means that the values are in order. The median of a sorted set of data values (n) is defined
MENU Function: The MATLAB also has a built-in function known as menu which will display a figure Window with push buttons for the choices. The very first string passed to the
Need of a nested loop: How would we sum each individual column, rather than getting an overall sum? Answer: The programming technique would need a nested loop in whi
Illustrations of Sequential search: The two illustrations of calling such function is as shown below: >> values = [85 70 100 95 80 91]; >> key = 95; >> seqsearch
Core Objects: The Core Objects in MATLAB are the very fundamental graphics primitives. The description can be found under the MATLAB Help: Under the Contents tab, click the Ha
Roots function - Polynomials: The roots function in MATLAB is used to find the roots of an equation represented by a polynomial. For illustration, for the mathematical functio
