Illustration of Writing to files:
Here is the other illustration in which a matrix is written to a file. At First, an arbitrary 2 × 4 matrix is generated, and then it is written to the file by using the format string %d %d\n', that means that each column from the matrix will be written as an individual line in the file.
>> mat = randint(2,4,[5 20])
mat =
20 14 19 12
8 12 17 5
>> fid = fopen('randmat.dat','w');
>> fprintf(fid,'%d %d\n',mat);
>> fclose(fid);
As this is a matrix, the load function is used to read it in.
>> load randmat.dat
>> randmat
randmat =
20 8
14 12
19 17
12 5
>> randmat'
ans =
Transposing the matrix will show in the form of the original matrix. When you want this to start with, the matrix variable mat can be transposed before using the fprintf to write to the file. (Obviously, it would be much easier in this situation to just use save rather than!)
Labels and Prompts: The script loads all the numbers from file into a row vector. It then splits the vector; it stores the initial element that is the experiment number in a v
Three-Dimensional Plots: The MATLAB has many functions which will display three-dimensional plots. Most of these functions have similar name as corresponding two-dimensional p
Differentiation: The derivative of a function y = f(x) can be written as follows or f '(x) and is defined as the rate of change of the dependent variable y with respe
Use of logical vector: Determine how many elements in the vector vec were greater than 5, the sum function can be used on the resulting vector isg: >> sum(isg) ans =
Concatenation: The String concatenation means to join the strings altogether. Of course, as strings are merely vectors of the characters, the technique of concatenating vector
Error-checking for integers: illustrations of running this script as shown below: >> readoneint Enter an integer: 9.5 Invalid! Enter an integer: 3.6 Invalid
User input in the while loop: Here is an illustration of running this script: >> readonenum Enter a positive number: -5 Invalid! Enter a positive number: -2.2
bar and barh functions: For a matrix, the bar and barh functions will group altogether the values in each and every row. The illustration is as shown: rm = randint(2,4,[1
Symbolic Expression The solve function solves an equation and returns the solution(s) as symbolic expressions. The answer can be converted to numbers by using any numeric funct
Function isreal - complex numbers: The function isreal returns 1 for logical true when there is no imaginary part of the argument, or 0 for false when the argument does have a
