Varying parameters in if statement

Hi! I would like to create a conditional statement where the parameters of my if statement is changing. Is it possible to vary the parameters in the if statement?
Here is an example:
x10=1;
i=10;
word='x';
if ('%s%d~=1',word,i)
v='not working'
end
I tried this one but it is not working, any suggestion on how to make it work?

Here is the closest I can get to the code that I think you wanted:
x10=1;
i=10;
word='x';
% Create a "pass/fail" variable that will be tested.
eval(sprintf('PF = %s%d~=1;',word,i))
% Do the test
if PF
v = 'not working'
end

x10=1;
i=10;
word='x';
% Create a "pass/fail" variable that will be tested.
eval(sprintf('if %s%d~=1, v = ''not working''; disp(v); end ',word,i))
If you don't actually need to display the 'not working' text, then you can get rid of the
disp(v)
statement inside the eval() statement.

Something like:
mynum = 2; % change to mynum = 1
x10 = 1;
word = 'x';
i = 10;
if (eval(genvarname(strcat(word,num2str(i)))) == mynum)
fprintf('x10 is %d\n', mynum);
else
fprintf('x10 is not %d\n', mynum);
end
