### Test Suite

Test Status Code Input and Output
1   Pass
%% XXX = @(z)cos(z); assert(isequal(wine_tester(XXX),'old wine')) % cos

2   Fail
%% XXX = @(z)sqrt(1-cos(z)^2); assert(isequal(wine_tester(XXX),'old wine')) % sin

Error: Inputs must be a scalar and a square matrix. To compute elementwise POWER, use POWER (.^) instead.

3   Fail
%% XXX = @(z)cos(z)^2+10; assert(isequal(wine_tester(XXX),'new wine')) %

Error: Inputs must be a scalar and a square matrix. To compute elementwise POWER, use POWER (.^) instead.

4   Fail
%% XXX = @(z)log10(10*z)-1; assert(isequal(wine_tester(XXX),'old wine')) % log10

Error: Assertion failed.

5   Pass
%% XXX = @(z)sin(log10(z)*0+z); assert(isequal(wine_tester(XXX),'old wine')) % sin

6   Pass
%% XXX = @(z)sin(log10(z)); assert(isequal(wine_tester(XXX),'new wine')) %

7   Pass
%% XXX = @(z)cosd(z); assert(isequal(wine_tester(XXX),'old wine')) % cosd

8   Pass
%% XXX = @(z)exp(z); assert(isequal(wine_tester(XXX),'old wine')) % exp
