quaterions to string in matlab

i need a function like num2str for quaterions in matlab u can help me

[James Tursa]

How are your quaternions stored? Can you give an example of an input and desired output?

[AMAL targhi]

for example i want to display a quaterion intp disp

for example my quaterion is dynamique his form is = [ a b c d ] and i need to display it into a loop

disp(['Iteration: ', num2str(n), ' / ' 'Error: ', num2str(network.sumsqrerr(n) / size(inputs, 2))]);

network.sumsqrerr(n) " it s a quaternion'

I still don't know how your quaternions are stored. Maybe a class object? However, one thing you might try is converting it to a double first before calling num2str. E.g., if network.sumsqrerr(n) is a quaternion, then maybe try this formulation:

num2str(double(network.sumsqrerr(n)) / size(inputs, 2))
