WRITING A PROGRAM\par
Command window is for individual commands\par
Write as a text file .m\par
Click on create a new program, opens Matlab editor\par
Save, give a name\par
Can run program (called script) by clicking green run button).\par
Runs all commands, could right click program and hit run\par
Can edit and change.\par
Can type script name in command window to run.\par
Must be in current folder or search path.\par
Current folder displayed up top.\par
Can open by double clicking or using edit\par
use % for commenting\par
x = (1:1000)'; % column vector\par
for k=1:5\par
y(:,k)=k*log(x);\par
end\par
plot(x,y)\par
\line\par
want to create function files\par
start with function keyword\par
have a function name that should match name of file\line can pass in values\par
function simple(maxLoop)\par
x=(1:1000)' % column vector\par
for k=1:maxLoop\par
y(:,k)=k*log(x);\par
