Error handling is just as it sounds – a way for your program to respond when it encounters an error. When you have statements in your code that could possibly generate unwanted results, put those statements into a try-catch block that will catch any errors and handle them appropriately.

When you rerun your program, MATLAB pauses execution at the breakpoint and enables you to step through the program code. The example below shows a try-catch block within a sample function that multiplies two matrices: function matrixMultiply(A, B) try X = A * B catch disp '** Error multiplying A * For example:>> warning on verbose >> delete sadfsefgsdfg Warning: File 'sadfsefgsdfg' not found. (Type "warning off MATLAB:DELETE:FileNotFound" to suppress this warning.)Within the exception-handling part, we could check the specific exception If its called more than 100 times in a given run then if/else may be a better bet.

There are some cases where my .dat file is corrupted and the function cannot convert and an error occurs, stopping the loop. After we have finished processing, we can return the warning state to its previous value.For example:% Set a couple of warnings to temporarily issue errors (exceptions) s = warning('error', 'MATLAB:DELETE:Permission'); warning('error', Had I used the newer syntax, the code would not have worked on old Matlab releases; this way it does, subject to the availability of the above-mentioned undocumented warning(‘error',…) trick.
