function result = your_function_name(x, matrix) result = ((2*matrix)^(-1/2))*(x'); Then you can call your function like this: x = [x1 x2]; matrix = [h11 h12; h21 h22]; your_function_name(x, matrix); Or you can use an anonymous function. x = [x1 x2]; m...
I created a symbolic function in MATLAB R2021b using this script with the goal of solving an ODE. syms phi(x) lambda L eqn_x = diff(phi,x,2) == -lambda*phi; dphi = diff(phi,x); cond = [phi(0)==0, dphi(1)==0]; % this is the line where the problem starts d...
Symbolic(符号):利用逻辑推理符号表达。例如下面的规则可表达为:“AB>C”。 Indexed(编号):用编号和模糊推理框图。 格式: ruleview(a) ruleview(a)界面: ruleview函数打开规则观测器的GUI如图6-5所示。说明: 利用ruleview(a)可打开文件a.fis规则善的规则观测器,从中可对a.fis文件的FIS结构画出模糊推理框图,...
错误使用 sym>convertChar Character vectors and strings in the first argument can only specify a variable or number. To evaluate character vectors and strings representing symbolic expressions, use 'str2sym'. 出错sym>tomupad (第 1608 行) S = convertChar(x); 出错sym (第 400 行) S.s = tom...

polyinterp The polyinterp function also works correctly with symbolic variables. 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 ...
