matlab错误：Input argument "x" is undefined.Error in ==> overlapsave at 2 Lenx=length(x);源代码是：function y=overlapsave(x,h,N)Lenx=length(x);M=length(h);if N

matlab中else if语句只执行了第二句,程序没问题,逻辑上哪里有错误?weight=input('the weight of your purse:');if weight matlab 求和有错误 matlab 省略号 出现错误 matlab 错误 到底 matlab一个定义值只能用于一个公式的计算吗?“W=input('input W(kg)=');mw=input('input mw(kg/h)=');V0=input('input V0=');T0=input('input T0=');P0=input('input P0=');P0v=input('input P0v=');M0a=((P0-P0v)*V0)/(287*T0);M0v=(P0v*VO)/(461*T0 matlab出现Too many input arguments错误我定义了一个上近似的代码,保存为,upper.m 但是总是出现Too many input arguments的错误function T=A(a,b)result=ind(a);T=[];[g,h]=size(result);for k=1:gw=result(k,:);w(w==0)=[];if(intersect( MATLAB取出矩阵中元素的问题inputr=input(:,:,1)inputg=input(:,:,2) matlab中拉氏变换问题>> f=1;>> F=laplace(f)Undefined function or method 'laplace' for input arguments of type 'double'.想求常数1的拉氏变换.错误在哪里?如何修改? matlab错误：Input argument x is undefined.Error in ==> overlapsave at 2 Lenx=length(x);源代码是：function y=overlapsave(x,h,N)Lenx=length(x);M=length(h);if N 关于matlab的switch语句,请帮我找找错误price = input('input price');switch fix(price/100) case [0, 1] rate = 0; case [2, 3, 4] rate = 0.03; case [5, 6, 7, 8, 9] rate = 0.05; otherwise rate = 0.1;end 用matlab画三维图出错误,下面是程序clc;clear;x=0:0.1:60;%预测点离排放点的距离,my=0:0.1:20; %预测点离排放点的横向距离,mCp=input('污水中污染物浓度mg/l=');Qp=input('污水流量m3/s=');Ck=3.77*10.^-6; %污染物 matlab非线性方程的求解我按照书本上的例题输入进去,但是上面显示了 x为定义变量.程序如下function fx=fun(x)fx=x-10.^x+2;z=fzero('fun(x)',0.5)在matlab中显示的错误如下：Input argument x is undefined.Error in matlab 求余乘式的错误不解,好长时间没用matlab了 matlab中老是提示函数定义错误, matlab画图时的坐标出现错误? MATLAB/SIMULINK的一个错误Derivative input 1 of 'mac/Subsystem/Integrator6' at time 0.08029144179417799 is Inf or NaN.Stopping simulation.There may be a singularity in the solution.If not,try reducing the step size (either by reducing the fixed s matlab中关于EXP的错误 急啊x=(0:0.1:2);y1=(1/sqrt(2*pi))*(exp^(-(x^2)/2));h1=subplot(2,2,1);plot(x,y1)title('标准正态分布的概率密度曲线') 运行说是?
