[A, b] = equationsToMatrix(f1, [a1, a2, a3, a4, a5]);这里，A是系数矩阵，b是常数向量。如果你已经有了线性方程组的表达式，可以通过手动提取每个方程中的系数来构建系数矩阵。例如，对于以下方程组：eq1 = 6*a1 + 4*a2 + 7*a5 == -1;eq2 = a1 + 3*a2 + 5*a3 + 7*a4 == 2;c

问非线性方程组的MATLAB，equationsToMatrixENfzero函数可以用于求一个一元方程的根。通过用于指定起始区间的单元素起点或双元素向量调用该函数。如果为fzero提供起点x0，fzero将首先搜索函数更改符号的点周围的区间。如果找到该区间，fzero返回函数更改符号的位置附近的值。如果未找到此类区间，fzero 返回 NaN。或者，...
