求文matlab这个要测试要怎么写？

Question

first_test.m

function z=first_test(x,y)

 

% Add a line of code below that will compute matrix z as matrix x times matrix y.

% Do not change the name of the file or the function line in any way, it would not run.

% You may want to write another function to test this function.

end

 

test input:
x =
-0.6490 -0.7585 -0.8456
1.1812 -1.1096 -0.5727
y =
-0.5587 0.5864
0.1784 -0.8519
-0.1969 0.8003


trying to run z=first_test(x,y)
Output argument "z" (and maybe others) not assigned during call to "first_test".

x = [-0.6490 -0.7585 -0.8456;
       1.1812 -1.1096 -0.5727];
y = [ -0.5587 0.5864;
        0.1784 -0.8519;
        -0.1969 0.8003];

z = x * y;

disp(z);

这段代码将计算两个矩阵的乘积，并将结果输出。
