Error using plot Vectors must be the same length.

x = -10:0.4:10;

b = 2;c = 0;

mf1 = gbellmf(x,[2 b c]);

mf2 = gbellmf(x,[4 b c]);

mf3 = gbellmf(x,[6 b c]);

mf = [mf1 mf2 mf3];

subplot(221);

plot(x, mf);

title('(a) Changing "a"'); axis([-inf inf 0 1.2]);

Answer 1

Replace

mf = [mf1 mf2 mf3];

by

mf = [mf1; mf2; mf3];
