Since MATLAB executes only one case of any switch statement, variables defined within one case are not available for other cases. For example, if your current workspace does not contain a variable x, only cases that define x can use it: switch choice case 1 x = -pi:0.01:pi; case 2 %...

Error: Set case values to string instead of variables or constants. * Solution: Use variables or constants to define case values instead of strings. That way, we can keep more efficient control over the case values and avoid typographical errors. ...

In the C programming language, sometimes we may encounter variables that have different operations for different values. Such a variable is known as the switch case variable. We use the switch case because it has the switch statements and it replaces the if else-if statements in the C. The...
