Getting "Matrix dimensions must agree." warning, please help.

x = -1:0.3:2
y = -(1/((x-0.3).^2+0.01)+1/((x-0.9).^2+0.04))
plot(x,y)

when i run the program, i get this error

??? Error using ==> mldivide
Matrix dimensions must agree.

Error in ==> O4P9 at 12
y = -(1/((x-0.3).^2+0.01)+1/((x-0.9).^2+0.04))

why is that, what should i do to be able to plot? please help.

Add the necessary dots:

x = -1:0.3:2
y = -(1./((x-0.3).^2+0.01)+1./((x-0.9).^2+0.04))
plot(x,y)
