Create and Evaluate Symbolic Matrices as Functions of Two Variables Copy Command Copy Code Create a 2-by-2 symbolic matrix with automatically generated symbolic functions as its elements. syms f(x,y) 2 f f(x, y) = Assign symbolic expressions to the symbolic functions f1_1(x,y) and f2...
When you work with many symbolic functions, you should declare that your variables are symbolic.Create a script file and type the following code −syms x %symbolic variable x syms y %symbolic variable x % expanding equations expand((x-5)*(x+9)) expand((x+2)*(x-3)*(x-5)*(x+7)...
此外,传感器噪声特性通常是未知的,但测量值限制在某些区间内。在这项工作中,我们提出了两种解决人群跟踪问题的方法——一种是使用盒子粒子滤波方法,另一种是使用卷积粒子滤波方法。开发的滤波器可以以优雅的方式处理测量起源的不确定性,即解决数据关联问题。对于盒子粒子滤波器(PF),我们推导了在存在杂波的情况下的广义...

MATLAB中各个算术运算的相对精度大约是16位。相反，Maple的符号处理能力可以实现任何数位的运算。当缺省的数位增加时，每次计算就需要附加时间和计算机内存。Maple缺省为16位的精度。函数digits返回全局Digits参数的当前值。Maple缺省准确度可以由digits(n)来改变，其中n是所期望的准确度数位。用这种方法增加准确度的副作用...
For example, create symx = sym(’x’) Then evaluate and display the symbolic form of the interpolating polynomial with P = polyinterp(x,y,symx) pretty(P) produces -5 (-1/3 x + 1)(-1/2 x + 1)(-x + 1) - 6 (-1/2 x + 3/2)(-x + 2)x -1/2 (-x + 3)(x - 1...
First four column are the y axis values do not change last 4 rows are the x values and im converting them in a function Wavelength I am having an issue with my function. I am trying to pass my function a 4X178 matrix and evaluate is at each point for each row and save it into an...
Symbolic Math Toolbox provides a set of functions for solving, plotting, and manipulating symbolic math equations. You can generate MATLAB functions, Simulink function block, and Simscape equations directly from symbolic expressions or you can share your

>> M=sym( '[a,b;c,d] ') % create a symbolic matrix M M= [a,b] [c,d] 注意:1.建立符号数组时,最好用上函数sym 2.许多符号函数可以自动将字符转变为符号表达式。例如diff cos(x)也可以, >> diff x^2+3*x+5 % the argument is equivalent to ' x^2+3*x+5 ' 符号变量是符号表达式...
