Run-time or execution-time error:
The Run-time, or execution-time, errors are found whenever a script or function is executing. With most of the languages, an illustration of a run-time error would be trying to divide by zero. Though, in the MATLAB, this will create a warning message. The other illustration would be trying to refer to an element in an array which does not exist.
This script initializes a vector with 3 elements, but then tries to refer to the fourth. Running it prints the three elements in the vector, and then an error message is generated whenever it attempts to refer to the fourth element. Note that it gives a description of the error, and it provides the line number in the script in which the error happened.
>> runtime_ex

??? Tried to access vec(4); index out of the bounds because
numel(vec)=3.
Error in ==> runtime_ex at 6
disp(vec(i))
Function Stubs: The other common debugging method, which is used when there is a script main program which calls many functions, is to use the function stubs. A function stub
Input in a While Loop: The script below repeats the procedure of prompting a user, the reading in a positive number, and echo-printing it, as long as the user properly enters
Illustration of tracing a error: The one way of following the flow of function, or tracing it, is to use the echo function. The echo function, that is a toggle, will show each
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
Functions which return Values versus printing: Also, the function which computes and returns values (throughout the output arguments) does not generally print them; that is le
Polynomials: Simple curves are polynomials of various degrees, or orders. The degree is the integer of the highest exponent in the expression. The illustrations are as follows
Operation on file: We concentrate first on the fgetl function that reads strings from the file one line at a time. The fgetl functions afford more control over how the data is
Debugging Techniques: Any error in the computer program is called a bug. This word is thought to date back to the 1940s, whenever a problem with an early computer was found to
Execution of persistent variables: The functions can also be called from the script or from the Command Window, as shown here. For illustration, the functions are called first
Example of Core objects: The one core graphics object is a line that is also what the plot function produces. Here is an illustration of generating a line object, altering som
