I am using MATLAB livelink for a heat transfer problem. I am trying to define a function for density of the material used in my model. I use the following commands in MATLAB to make the function. I should also mention that Density.m file is also in the directory in which th...
1.你打开Matlab程序,左上角File---New---Function;2.将你看见的一些代码删了,然后将你上面的代码复制上去;3.文件名为simpson;4.然后在matlab里面输入simpson(20);括号里面的数字看你的需要填写

Open in MATLAB Online Hello, I am trying to experiment the usage of copyfile for copying a .jar file for source location to destination. I have written a test script that takes the jar file from the current location and move it to a destination folder "C:\Program Files\MATLAB\R2020b...

从上面程序看,如果这是一个完整程序,就不会有上面的提示。有上面的提示,很可能这只是一个大程序的一部分。一般情况下,只有在函数文件下才能定义子函数,在脚本文件下是不允许定义函数的。因此,这可能是在一个脚本文件内定义一个函数,就出现了错误提示。可把这段程序分出来,单独作一个文件保存。
function y=Ex0502(zeta)x=0:0.1:20;x=linspace(0,20,length(zeta));y=1-sqrt(1-zeta.^2).*exp(-zeta.*x).*sin(sqrt(1-zeta.^2).*x+acos(zeta));plot(x,y)end 按上面语句保存试试

第一次用matlab。 做一个最简单的实验,产生信号波形。 产生信号波形的方法有三种。 第一种就是funtool funtool的f和g是两个x的函数,分别显示。 我在输入f时,输错了。输成2sin(x),回车出现: ??? Error while evaluating uicontrol Callback. ??? Error using ==> sym.sym>char2sym ...
