MATLAB: Invalid escape sequence appears in format string. See help sprintf for valid escape sequences

fprintfsprintf

I have the following set of fprintf statements.
 magnaxialA=(Elem(i).Q(1,1)/1000);
 magnshearA=(Elem(i).Q(2,1))/1000;
 magnmomentA=(Elem(i).Q(3,1))/1000;
fprintf('\n\tStart Node\n')
fprintf('\Axial Force %f kN\n',abs(magnaxialA))
fprintf('\Shear Force %f kN\n',abs(magnshearA))
fprintf('\Moment %f kN-m\n',abs(magnmomentA))
But I keep getting the error message Invalid escape sequence appears in format string. See help sprintf for valid escape sequences

Best Answer

Get rid of the first backslash since \A, \S, and \M are invalid.
fprintf('\n\tStart Node\n')
fprintf('Axial Force %f kN\n',abs(magnaxialA))
fprintf('Shear Force %f kN\n',abs(magnshearA))
fprintf('Moment %f kN-m\n',abs(magnmomentA))
