How To Handle A Error In MATLAB

Error Handling In MATLAB

In any programming language, errors will lead to incorrect solutions. Coding errors should be avoided in MATLAB in order to execute the right output. In this article, we will explore the common errors in MATLAB that any user can make while coding the program.

Possible Errors While Writing MATLAB Function

1. The function code should always start with the word “function” which is an in-built command. The value required from the code can be entered with or without the bracket.
2. While saving the file, the file name should always be the same as the function name. If not, it would result in an error.
3. In the case of employing the variable, the function name should always end with the round brackets ( ) and the use of any other characters would result in an error.
4. The first line of the function should not be terminated with a semicolon (;).
5. The function must be completed with an “end” command.
6. Assigning the variable near the function command takes the value from the function code to the main code and you are likely to face an error that states “too many output argument error”.

Possible Errors While Writing The Main Code In MATLAB

1. All the loops inside the code must be terminated with an “end” command else it will display an error.
2. Always close the bracket while writing the code.
3. Save your code in the specified format.
4. The input values must be given to all the variables.
5. While calling the function, type the name you entered in the function code.
6. While plotting two arrays, both arrays must be of the same size.
7. Be aware of the variable cases which are being used.
8. While calling the function, give input arguments to the function.
9. The in-built commands that are being used in the code can be found by typing the first letter of the command and a tab.
10. The “sin” and “cos” term must be followed by d to specify the value in degree angle else MATLAB will assume the radians value of the angle by default.
11. While multiplying matrix in element-wise, use the dot operator (“.”).
12. Use quotations (‘ ’) when labeling the plot.
