How can I print sparse inputs using fprintf() in MATLAB 2013?

While using command: fprintf('%4g', p); fprintf('%4g', q);

(where, p=Real power & q=Reactive power)

it shows proper results in MATLAB 2009.

But with MATLAB 2013, it shows an error like: "Error using fprintf.

Function is not defined for sparse inputs."

How can I print required datas in MATLAB 2013 using "fprintf()" OR any other command ??

Even under Matlab 2009a fprintf does not work with sparse arrays. So the problem seems to be, that your p and q are sparse in MATLAB 2013, while it is not sparse in MATLAB 2009. How did you create these variables?

If the arrays are small, this will help:

fprintf('%4g', full(p));
fprintf('%4g', full(q));

I tried to use whatever u told like

fprintf('%4g', full(p)); fprintf('%4g',full(q));

though it shows the same error and I am using 14 bus system... tell me how to resolve it

@Dipesh Doshi: If you use the FULL() command, FPRINTF doe not get sparse inputs. Thefore you cannot get the same error message, at least not in this line. Please post an example with data, which reproduces the problem.

try this

fprintf('%4g',p); fprintf('%4g', q); fprintf(' %8.3f', full(Pij(p,q))); fprintf(' %8.3f', full(Qij(p,q)));

fprintf(' %4g', q); fprintf('%4g', p); fprintf(' %8.3f', full(Pij(q,p))); fprintf(' %8.3f', full(Qij(q,p)));

the error is in : fprintf(' %8.3f', Pij(p,q)); fprintf(' %8.3f', Qij(p,q)); and fprintf(' %8.3f', Pij(q,p)); fprintf(' %8.3f', Qij(q,p));
