Calling same function shows index in position 1 exceed array bounds even having same input matrix size?

Hi,

I am getting error in calling the same function with different matrix (of same size).

The function is: All input matrix is of same length.

[rate1] = rate(device,BandWidth,Tx,Power1,fading1,No_power);

[rate2] = rate(device,BandWidth,Tx,Power2,fading2,No_power);

• Note - If i change function name to rate1 and rate2. It not showing error. Donot Why??????????

If you do this:

   [rate] = rate(device,BandWidth,Tx,Power1,fading1,No_power);

Then rate is now a variable (the output from the function rate()). And the rate() function can no longer be called by saying rate(whatever). 'whatever' is treated like indexes into the variable rate rather than like inputs to the function rate(). So you may get an error the next time you use rate.

Changing the output variable to rate1 fixes it because the function rate() is not replaced in the workspace by the variable rate.

@Benjamin, I didnot understood clearly. What I understood is I cannot name output variable name same as function name.

For example: if i have run below function, who will i should run

SNR = 0:5:40;
Tx= (10^(-3))*db2pow(SNR);
for i=1:length(SNR)
    [r] = rate(device,BandWidth,Tx(i),Power1,fading1,No_power);
    ra(1,i) = r;
end

it's also giving me error.

Try this on the command line:

clear rate

when the loop is running 2nd time, it called the below function and then show index exceed in position 1.

function errorCallback = getExtendedErrorCallback(errorId)

end

Can you please copy the entire text of the error (all the red text) and post it here?

restoredefaultpath
rehash toolboxcache

Do the above commands once .

If the problem with getExtendedErrorCallback goes away, then there is something on your MATLAB path that is interfering with normal processing.

This problem got resolved when i make a new folder, write all the codes in that folder.

Thanks a lot for the help.
