一：你把这个文件夹拷贝一份 然后弄个新的干净的Foxmail先收信 二：在发件箱中删除邮件后进行压缩 三：推荐：在邮件夹当中新建若干个子邮件夹，将邮件分门别类的移动到这些子邮件夹当中，这样每个子邮件夹的大小都不会超过2G。其实这个工作应该在平时就做好，你可以通过建立“过滤器”将来自不同发件...
思路有点混乱，syms x;y=x^2-1;fsolve(y,-2);你算的是x=2,y=（-2）^2-1还是：-2=x^2-1 求x。如果是前者使用subs 如果是后者，直接写到一起
MATLAB Online에서 열기 For example, there is a function F(x) which has F(0) = 0 and F'(0) = 1. I want to calculate the value of the derivative G'(0) of G(x) = 1/F(x) (this is the example), how do I write the code?
R = subs(S) replaces all occurrences of variables in the symbolic expression S with values obtained from the calling function, or the MATLAB workspace.相当于于用值去替换符号表达式中的变量例如:The statementy = dsolve('Dy = -a*y')producesy =C2/exp(a*t)Then the st...
