How do I fix the error "Line 10: Parse error at 2: usage might be invalid MATLAB syntax"?

clc
Vb=[0 -12];
Va=(-18*cosd(60)-18*sind(60));
Vba=Vb-Va;
magnitude_Vba=norm(Vba);
Angle_Vba=atand(Vba(2)/Vba(1));
Abnormal=Vb(2)^2/100;
Ab=(-Abnormal-3);
Aa=2*cosd(60) 2*sind(60);--- this line is getting the error
Aba=Ab-Aa;
magnitude_Aba=norm(Aba);
Angle_Aba=atand(Aba(2)/Aba(1));

Answer 1

What is unclear about the error message? Clearly you're missing something between 2*cosd(60) and 2*sind(60), perhaps an operator. As it is, yes the line does not make sense.

Answer 2

[Star Strider]

You either need an arithmetic operator (addition, subtraction, muyltiplication, division or the element-wise vectorized versions of them) or create ‘Aa’ as a matrix.

Assuming you want it as a matrix, this will work:

Aa = [2*cosd(60) 2*sind(60)]; % --- this line is getting the error

and will work with the rest of your code (producing Angle_Aba=48.6), although I have no idea what you actually want to do.

[Heiland]

I was missing a "+" sign between the two. Now I keep getting an error for line 13 that says "index exceeds matrix dimensions"

[Guillaume]

Well, yes, since Aba has only one element, Aba(2) doesn't exist.

Clearly, you've made another mistake. Perhaps you should proofread your code.

[Star Strider]

Exactly.

What are your data, and what do you want to do with them?
