这是我用matlab画的图,为什么会出现两条线?我的程序如下：clear all;P=[0.036,0.036,0.036,0.037,0.040,0.038,0.044,0.051,0.063,0.080,0.102,0.128,0.163,0.211,0.262,0.321,0.386,0.458,0.547,0.627,0.723,0.815,0.916,1.029];I=[0.072,0.036,

你的对应点本来就是这样的啊.如果图形不对就是你的输入算错了.
plot(I,P,‘*-’);
你看一下你的点都对应在哪里

The function values at the interval endpoints must differ in sign.我用MATLAB计算f=x^2-2x-3在区间【-100,100】内的零点,为什么会出现这句话? 怎么用MATLAB画二次函数图象?为什么我在用MATLAB 的时候画二次图象的时候总是会出现错误?比方说:我画Y=X^2在X=(-5,5)之间的图象;x=linspace(-5,5,50);y=x^2;plot(x,y)Error using ==> mpowerMatrix must be square. 南极为什么会出现美丽的“南极之光”呢南极为什么会出现“南极之光”呢?这是我的作业, 用matlab求导结果得到很多个数字我只是求导为何会出现那么多神奇的东西…… 我的世界为什么会出现这个 为什么我会出现这样的情况? matlab的一个小问题.请问为什么会出现这个情况,/> 用matlab 循环语句画4个图,为什么只出现最后一个图? 我在VB中使用矩阵函数库MatrixVB的eig求特征值和特征向量,出现了这样的问题.特征向量与用matlab求的差了一个符号,这是为什么? matlab中为什么会出现NaN?是因为数据太小还是因为数据太大,或是因为不是数据?但是由公式计算出来的为什么会出现这种情况呢? 不锈钢焊丝430焊接的时候为什么会出现焊斑我用不同品牌为什么会出现这种问题! 为什么会出现台风?台风到底是怎么出现的? 在韩剧中,为什么会出现汉字呢我看了许多的韩剧,里面出现了中国字,这是为什么呢 为什么我在用vf上机练习的时候会出现这个情况?这是第六套题.可是我明明就是独占打开的啊?
