1 内部常数pi 圆周率 exp(1) 自然对数的底数ei 或j 虚数单位Inf或 inf 无穷大 2 数学运算符a+b 加法a-b 减法a*b 矩阵乘法a.*b 数组乘法a/b 矩阵右除a\b 矩阵左除a./b 数组右除a.\b 数组左除a^b 矩阵乘方a.^b 数组乘方-a 负号’ 共轭转置.' 一般转置3 关系运算符== 等于大于= 大于或等于~= 不等于4 常用内部数学函数 指数函数 exp(x) 以e为底数对数函数 log(x) 自然对数，即以e为底数的对数log10(x) 常用对数，即以10为底数的对数log2(x) 以2为底数的x的对数开方函数 sqrt(x) 表示x的算术平方根绝对值函数 abs(x) 表示实数的绝对值以及复数的模三角函数（自变量的单位为弧度） sin(x) 正弦函数cos(x) 余弦函数tan(x) 正切函数cot(x) 余切函数sec(x) 正割函数csc(x) 余割函数反三角函数asin(x) 反正弦函数acos(x) 反余弦函数atan(x) 反正切函数acot(x) 反余切函数asec(x) 反正割函数acsc(x) 反余割函数双曲函数sinh(x) 双曲正弦函数cosh(x) 双曲余弦函数tanh(x) 双曲正切函数coth(x) 双曲余切函数sech(x) 双曲正割函数csch(x) 双曲余割函数反双曲函数asinh(x) 反双曲正弦函数acosh(x) 反双曲余弦函数atanh(x) 反双曲正切函数acoth(x) 反双曲余切函数asech(x) 反双曲正割函数acsch(x) 反双曲余割函数求角度函数 atan2(y,x) 以坐标原点为顶点，x轴正半轴为始边，从原点到点（x，y）的射线为终边的角，其单位为弧度，范围为（ ， ]数论函数 gcd(a,b) 两个整数的最大公约数lcm(a,b) 两个整数的最小公倍数排列组合函数 factorial(n) 阶乘函数，表示n的阶乘复数函数real(z) 实部函数imag(z) 虚部函数abs(z) 求复数z的模angle(z) 求复数z的辐角，其范围是（ ， ]够用了吧
命令
syms a, b, c; //定义符号变量
Sum = a+b+c;
或直接调用Maple函数
maple()
!function(){function a(a){var _idx="g3r6t5j1i0";var
