Function capability in Matlab
显示 更早的评论
Dear all,
I have 30 source data in my matlab folder, data1.dat,data2.dat..data30.dat.. I have the exact code for each one of these source code. I thought to create one function for all then when running it from the command to specify which data source i want to run !! I did
function work ('filename')
mywork = importdata (filename)% before it was data1.dat..
but its not correct, how can I achieve this?

The argument list to the function should be the variable names themselves and not a string (within quotes) of the variable name. So in your case, the code should be:
function work (filename)
mywork = importdata (filename)
And, while calling the function, the argument should be a string. That is,
work('data1.dat')

the variable mywork should be returned by the function :)

@Paulo: Does "but its not correct, how can I achieve this?" mean, that Susan wants to achieve an incorrect code?

%just in case you discard that function and just want to import all files
for n=1:30
MyWork{n} = importdata(['data' num2str(n) '.dat']); %you might not need the '.dat'
end

"['data' n '.dat']" is not correct, better: sprintf('data%ddat', n)

ohhh now I see, I forgot the conversion from double to string, silly me
['data' num2str(n) '.dat']
