--description--
实现基本的元素矩阵 - 矩阵和标量矩阵运算。
实行：
:: *另外
:: *减法
:: *乘法
:: *分裂
:: *取幂
第一个参数是要执行的操作，例如：用于矩阵加法的“m_add”和用于标量加法的“s_add”。第二和第三参数将是要在其上执行操作的矩阵。

operation是一种功能。
assert(typeof operation === 'function');
operation("m_add",[[1,2],[3,4]],[[1,2],[3,4]])应返回[[2,4],[6,8]] 。
assert.deepEqual(
operation(
'm_add',
[
[1, 2],
[3, 4]
],
[
[1, 2],
[3, 4]
]
),
[
[2, 4],
[6, 8]
]
);
operation("s_add",[[1,2],[3,4]],[[1,2],[3,4]])应返回[[3,4],[5,6]] 。
assert.deepEqual(
operation(
's_add',
[
[1, 2],
[3, 4]
],
2
),
[
[3, 4],
[5, 6]

);
operation("m_sub",[[1,2],[3,4]],[[1,2],[3,4]])应返回[[0,0],[0,0]] 。
assert.deepEqual(

operation("m_mult",[[1,2],[3,4]],[[1,2],[3,4]])应该返回[[1,4],[9,16]] 。

operation("m_div",[[1,2],[3,4]],[[1,2],[3,4]])应返回[[1,1],[1,1]] 。
assert.deepEqual(

[
[1, 2],
[3, 4]

[1, 1]

operation("m_exp",[[1,2],[3,4]],[[1,2],[3,4]])应返回[[1,4],[27,256]] 。
assert.deepEqual(
