+# 矩陣乘法
+
+矩陣乘法是在數值計算中相當基本的運算方式，矩陣乘法的效率常常也決定了數值軟體的效能。矩陣乘法中的每個元素計算依循以下式子：

+
+## 測試
+
+```julia
+A = [1 2; 3 4]
+B = [1, 0]
+C = [1, 3]
+@test all(multiply(A, B) .== C)
+```
+
+### 測試資料
+
+以下測試資料中，請計算 `A`、`B` 相乘，並比對正確答案 `C`。
+
+```julia
+A1 = rand(5, 5)
+B1 = rand(5, 5)
+C1 = A1*B1
+
+A2 = rand(1, 5)
+B2 = rand(5, 1)
+C2 = A2*B2
+
+A3 = rand(3, 4)
+B3 = rand(4, 5)
+C3 = A3*B3
+```
