matlab报错Function definitions are not permitted at the prompt or in scripts.麻烦帮修改程序能运行
这是我的程序
function []=expand(q,a,d,t,v0)
R=(q*t/(a*pi/6+5000*pi))^(1/3);
q=1;a=14363.384;d=0.3;t=100000;v0=3.6;
for i=0:24:t/3600
if (d*(i/24))

看了你的问题,我发现,你是把函数在命令行输入运行了,先用编辑器编辑保存,然后再在命令行引用吧

再问：我保存了那个函数，可是出现了下面这个问题 Attempt to execute SCRIPT filename as a function: C:\Users\蕊竹\Documents\MATLAB\filename.m
再答：这么说吧，matlab是有一个工作区间的，你把这个文件保存在工作区间，运行的时候文件也需要在工作区间，还有，q=1;a=14363.384;d=0.3;t=100000;v0=3.6;这行删掉还有axis([-10,15,-10,25,0,10]);时会做出两个图，可以改成axis([-10,15]); 最后命令行输入 expand(1,14363.384,0.3,100000,3.6)
