create branch code depending on variable type in matlab

To create a branch code depending on variable type in MATLAB, you can use the class function to check the variable's class.

Here's an example code:

main.m
if isa(myVariable, 'double')
    % code for double type variable
elseif isa(myVariable, 'char')
    % code for character type variable
elseif isa(myVariable, 'logical')
    % code for logical type variable
elseif isa(myVariable, 'cell')
    % code for cell type variable
else
    error('Unsupported variable type!')
end
320 chars
12 lines

In this code, isa function is used to check the variable's class. The if-elseif statements will route to specific code depending on the variable type.

The else statement is optional, but it will help to catch unsupported variable types and return an error message.
