a = app.val1.Value;
b = app.val2.Value;
app.result.Value = a & b;
Error using matlab.ui.control.internal.model.AbstractNumericComponent/set.Value (line 110) 'Value' must be a double scalar.

It appears that the val1 and val2 are text type edit field, therefore a and b will have char class. Whereas result is a numeric edit field. If a and b have multiple characters then a&b will be an array and thus cannot be assigned to a scalar numeric field. You will need to take care of the type of edit field, you are trying to assign the value.
