In matlab's symbolic math toolbox , you can work with symbolic matrices using thesymfunction to create symbolic variables and expressions , Here's a basic example of how to calculate a matrix symbolically; % Define symbolic variablessymsabcd;% Create a symbolic matrixA=[ab;cd];% Defi...
matlab符号与数值转换(Matlabsymbolandnumericalconversion)matlab符号与数值转换(Matlab symbol and numerical conversion)a = 1/3;格式大鼠;一 结果果然是= 1/3只(一)一旦创建了一个符号表达式,或许想以某些方式改变它;也许希望提取表达式的一部分,合并两个表达式或求得表达的数值。有许多符号工具可以帮助完成...
除了syms类型,inline和匿名函数也是该Symbolic Math Toolbox的常客。 1 inline与匿名函数(Anonymous Functions) 利用inline函数生成inline object的简单例子如下: f = inline('a*x^2 + b*x + c', 'a', 'b', 'c', 'x') f(1, 2, 3, 1) 结果为: f = Inline function: f(a,b,c,x) = a * ...
你的程序中有判断两个符号量大小的代码,但符号类型(sym)是不能比较大小的。gt是大于号的函数形式,也就是说,gt(a,b)与a>b是相同的。

1.5 Symbolic Matrices Use matrices containing symbolic values. Use Existing Symbolic Variables >>symsabcA=[abc;cab;bca]A=[a,b,c][c,a,b][b,c,a] To check if the sum of the elements of the first row equals the sum of the elements of the second column, use the isAlways function: ...
See this link for how to correctly declare a function in MATLAB. Put this in a separate file named "your_function_name.m" function result = your_function_name(x, matrix) result = ((2*matrix)^(-1/2))*(x'); Then you can call your function like this: x = [x1 x2]; ...
其实很好理解啊。当你执行求积分函数后 F3变成了sym符号类型,这种类型是不能参与逻辑判断的。所以你应该改成F3=double(abs(F1-F2));
I'm pretty new to symbolic functions andsymsvariables in MATLAB, why is MATLAB rejecting this code? The similar code that I tried that worked was: syms f(x); syms y; f(x) = (x^2) + y; integral = int(f, x, [03]);disp(integral); ...
