How to fix error using horzcat when trying to display?

I'm trying to learn matlab. How am I supposed to display to values in the same line without getting horzcat error? What am I doing wrong? Any help is appreciated.

try with sprintf

c = (a.^2 + b.^2).^(1/2);
d = atand(a./b);
e = d;
d(d<0)=360+d(d<0);
X = sprintf('The resultant force is %0.1f kN and directed %0.1f degrees measured counterclockwise from the positive x-axis\n',c,d)

Hi! Thank you for answering. But may I ask why the supposed values for "d" changes in the sentence? Thank you.
