Logical errors:
The Logical errors are more complicated to locate, as they do not result in any error message. The logical error is a mistake in reasoning by the programmer, but it is not a fault in the programming language. An illustration of a logical error would be dividing by 2.54 rather than of multiplying in order to convert inches to centimeters. The outcome printed or returned would be wrong, but this may not be obvious.
All the programs must be robust and must wherever possible anticipate potential errors, and guard against them. For illustration, whenever there is input into a program, the program must error-check and make sure that the input is in the accurate range of values. Also, before dividing, the denominator must be checked to make sure that it is not zero.
In spite of the best precautions, there are bound to be errors in the programs.
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
Example of Mode When no value appears more often than any other, the smallest value in the vector will be the mode of the vector. >> shortx = [2 5 1 4]; >> mode(shortx

Index vector: The index vector is then used as the indices for original vector. To get grades vector in ascending order, the indices used would be grades (2), grades (5), and
Illustration of Customizing plots: Illustration, the bar and barh functions by the default place a width of 0.8 between bars. Whenever called as bar(x,y), the width of 0.8 is
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
Properties of the text box - graphics objects: By using get will show properties of the text box, the illustration is as shown below: >> get(thand) BackgroundColor
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
