谁能给我解释一下matlab的运行结果Ks{1}ans =2 3 41 3 52 6 7>> r=[3 1 2]r =3 1 2>> K=Ks{1}(r,r)K =7 2 64 2 35 1 3K=Ks{1}(r,r) 这个语句不明白,矩阵K是怎么算出来的? 帮我把以下命令在matlab下运行一下,把运行结果发上来!t=[0.25,0.5,1,1.5,2,3,4,6,8];c=[ 19.21,18.15,15.36,14.10,12.89,9.32,7.45,5.24,3.01];y=log(c);aa=polyfit(t,y,1); a=aa(1)b=aa(2)k=-ad=300;v=d/exp(b) cc=exp(b)*exp(a*t);plot(t,c,'k+' 如何终止matlab中正在执行的指令 矩形房间的周长是28米,宽是6米,则对角线长是几米 矩形房间的周长是20m,宽是4m,则对角线长是几米? 室内量房卷尺最好用几米的 英译汉,1句A.B.C在外偷偷摸摸,碰到了D,出现了这么一个英文句子：something about their guilty faces cought D's eye. 数论求证：2222的5555次方加5555的2222次方能被7整除 一句英译汉!There is at least a good point about living there.My working place is just a few blocks away from where live.I don’t have spend much time in commuting everyday. 1.求所有满足3|2^n+1的正整数n.2.求2^1000除以13的余数.3.求证7|(2222^5555+5555^2222)4.设n为自然数,若(19n+14)与(10n+3)模83同余,则n的最小可能值是（）A.4 B.8 C.16 D.325.试证明：对于一切自然数n,都有6|(n^3+11 求一句英译汉Don't get me wrong it is a perfectly lovely hotel with the suites more than acceptable however the perception that is provided through the marketing is not near the reality. 英译汉一句they missed opportunitie to question falsely limiting assumptions or to generate significantly different alternatives.they是指 太过缺乏争论的领导层主要是falsely limiting assumptions的意思? 一句英译汉.America has assimilated many people from Europe. matlab计算四重积分问题,如何比较简单的计算四重积分呢?必有重谢>> x=14*sin(pi/8);>> y=15-14*cos(pi/8);>> syms s t m n;>> int(int(int(int('1./((((x-m).^2+y.^2+n.^2).^0.5).*(((s-m).^2+225+(t-n).^2).^1.5))',s,-0.15,0.15),t,-0.15,0 用正比例解把1.5米长的竹竿直立在地上,量得它的影长1.2米.同时量得楼房的影长是6.4米.这幢楼高几米? 大树旁边立一根3米长的竹竿,测得竹竿影长2.4米,同时测得大树影长3.6米,大树高几米 测量小组,测得一楼房的影长21.6米,同时把2米的的竹竿立在地上,测得影长1.8米,求这一栋楼的高度 一根竹竿长4米,直立在地面上,量的它的影长是2.5米,在同一时刻,又量的一座楼房的影长是17.5米,这座楼房 如果三角形的两条边的长分别是12厘米和9厘米,那么第三边长可能是多少厘米?（第三条边也是整厘米） 如果三角形的两条边的长分别是12厘米和9厘米,那么第三条边的长可能是多少厘米?（第三条边也是整厘米） 线性代数:已知AB=C且C可逆.可由|AB|=|C|推出|A||B|=|C|,从而推出|A|不等于0可逆,与|B|不等于0可逆吗? 英语同步检测与评估第四五页答案 方阵的特征值为实数,为什么特征向量一定为实向量 A为n*n的奇异实数矩阵,b为n*1的实数矩阵,求Ax=b中x我用matlab的pinv(A)*b所得到x,与用C++编程实现的全选主元消法（参考《C常用算法程序集》）得到的结果不一样那?而且相差蛮大的.为什么那?另外 they were talking the tv play为什么不加about While they were talking ,the bell rang.为什么后面不用过去进行时而用一般现在时 将下列句子改成否定句、改成一般疑问句并做肯定回答.I was born in 1996.____________________ ____________________ ____________________I met him yesterday._________________________ _________________________ ________________________ 求向量组的轶...轶到底是什么啊...[1,3,-22,0 43,1,5][1,1,21,2,31,3,4][1,-2,-3-5,10,15]这三个向量组的轶...轶和主元（pivot）有什么关系？ 列出我国三十四个省的行政单位、全称、简称、省会.
