Because a char array is an array of values in Matlab, you are trying to compare an array of values to another array. If what you want is comparing strings you should be using strcmp.
function pushforsalary1_Callback(hObject, eventdata, handles)
Career=get(handles.careerbox1,'String');
if strcmp(Career , 'Athlete')
listofsalaries = [20000 50000 60000 70000 90000];
salopt=randi(5);
handles.salarybox1.String = listofsalaries(salopt);
if strcmp(Career , 'Entertainer')
listofsalaries = [20000 50000 30000 40000 80000];
salopt=randi(5);
handles.salarybox1.String = listofsalaries(salopt);
end
You could also use switch, case in this context:
function pushforsalary1_Callback(hObject, eventdata, handles)
Career=get(handles.careerbox1,'String');
switch Career
case 'Athlete'
listofsalaries = [20000 50000 60000 70000 90000];
salopt=randi(5);
handles.salarybox1.String = listofsalaries(salopt);
case 'Entertainer'
listofsalaries = [20000 50000 30000 40000 80000];
salopt=randi(5);
handles.salarybox1.String = listofsalaries(salopt);
end
