loop txt files and save files

I do not have much knowledge in Matlab, but want to do the following, and need help.

I have two excel files, each has five columns of data. I need to add each column data in these two files with varying percentages in a loop, and save the new data in a series of files with the percentage in the files' names. Example:

%%%%%%%input data1%%%%%%%%%%%%%%%
data1=importdata('rawdata1.txt');

f1=data1(:,1);
e11=data1(:,2);
e12=data1(:,3);
u11=data1(:,4);
u12=data1(:,5);


%%%%%%%input data2%%%%%%%%%%%%%%%
data2=importdata('rawdata2.txt');

f2=data2(:,1);
e21=data2(:,2);
e22=data2(:,3);
u21=data2(:,4);
u22=data2(:,5);

%%%%%%%%%%%%%%%composite data%%%%%%%%%%%%

for x=0:0.1:1

data="Data"+x

f=x*f1+(1-x)*f2;
e1=x*e11+(1-x)*e21;
e2=x*e12+(1-x)*e22;
u1=x*u11+(1-x)*u21;
u2=x*u12+(1-x)*u22;

%%%%%%%%%save in data
data(:,1)=f;
data(:,2)=e1;
data(:,3)=e2;
data(:,4)=u1;
data(:,5)=u2;

xlswrite('data',data);

end;

You do not need 5 different variables for that. You could use

d1 = data1(:,1:5);
d2 = data2(:,1:5);

for x = 0:0.1:1
    data = d1 .* x + d2 .* (1-x);
    filename = sprintf('data%2.1f.xls', x);
    xslwrite(filename, data);
end

I tried, only got one file with the name of "filename"...

What is the part 'data%2.1f.xls'? What is "%2.1f"?

got the meaning of the symbol, but I tried, only got one file with the name of "filename"...not filename of "datax", and I expect to have 11 files with filenames of data0, data0.1, data0.2....

[madhan ravi]

 d2 = data2(:,1:5);

[madhan ravi]

 >> for x = 0:0.1:1
        filename = sprintf('data%2.1f.xls', x)
 end

 filename =

    'data0.0.xls'

 filename =

    'data0.1.xls'

 filename =

    'data0.2.xls'

 filename =

    'data0.3.xls'

 filename =

    'data0.4.xls'

 filename =

    'data0.5.xls'

 filename =

    'data0.6.xls'

 filename =

    'data0.7.xls'

 filename =

    'data0.8.xls'

 filename =

    'data0.9.xls'

 filename =

    'data1.0.xls'

Notice that what I posted is

    xslwrite(filename, data);

What you did instead is

    xslwrite('filename', data);

Thank Walter and Madhan a lot for the great help!
