1   Pass
x = 'X= A1 + A2*(Y1 + A3*Y123) ;' ; y_correct = {'Y1', 'Y123'} ; assert(isequal(your_fcn_name(x),y_correct))

y = 1×2 cell array {'Y1'} {'Y123'}

2   Pass
x= 'X= A + B*Y1*exp( C + D*Y12**2)' ; y_correct = {'Y1', 'Y12'} ; assert(isequal(your_fcn_name(x),y_correct))

y = 1×2 cell array {'Y1'} {'Y12'}

3   Pass
x= 'X= A + B*log( Y1 + 2) ; Z= atan( C + D*Y3*exp( C + D*Y12**2)' ; y_correct = {'Y1', 'Y12', 'Y3'} ; assert(isequal(your_fcn_name(x),y_correct))

y = 1×3 cell array {'Y1'} {'Y12'} {'Y3'}
