convert a variable parameter to 'string' in matlab

does anyone know how can a variable parameter convert to string? for example in under case, i parameter, (that, is a variable parameter) needs to be a variable string:

for i=1:10
lable=['input''''  i  ''' ];
     [r,'''i''']=xlsread(lable);
end

that i want to read input1 , input2,....,input10 and put them respectively r1,r2,..,r10

thanks let me check now

[mohammad]

i studied sprintf and eval, sorry i am beginner in Matlab, why matlab errores for :sprintf('A%d', i)=sprintf('xlsread(lableinput%d)', i)

this is for

A1=(input1.xls)

A2=(input2.xls)

.

Don't Do That!

basename = 'labelinput';

for i = 1:10

A{i} = xlsread(sprintf('%s%d.xls', basename, i));

end

Then use A{1} instead of A1, A{2} instead of A2, and so on.

What you are trying to do in making A1, A2, and so on, almost always runs in to problems.

so nice, perfect

now i need in every loop it shows : fprintf(' finished checking of input' 'i')

for example after A1=input1.xls shows:finished checking of input1

and after A2=input2.xls shows:finished checking of input2

but i dont know how putting variable (i), in fprintf

[mohammad]

i mean this:

for i = 1:10

A{i} = xlsread(sprintf('%s%d.xls', basename, i));

fprintf(' finished checking of input' 'i')

end

[mohammad]

and you are right Walter i dont need trying to make A1, A2

[Walter Roberson]

fprintf('finished checking of input %d\n', i);

[mohammad]

so thanks Walter

you really give a lot helps

for last question:

how can put variable in this speech:

NET.addAssembly('System.Speech');

speaker = System.Speech.Synthesis.SpeechSynthesizer();

speaker.Rate = 1;

speaker.Volume = 100;

speaker.Speak(['finished checking input'''i'''']);

[Walter Roberson]

speaker.Speak(sprintf('finished checking input %d', i));

[mohammad]

great, perfect!
