Dimensions do not agree??

Hi,

I have the following equation in Matlab:

F=(2/3.14)*ACos(exp(-(((B/2)*(1-(X)))/((X)*sin(Phi)))));

where

X =

    0.1111
    0.2222
    0.3333
    0.4444
    0.5556
    0.6667
    0.7778
    0.8889
    1.0000

and

Phi =

    0.7684
    0.5628
    0.4290
    0.3416
    0.2819
    0.2392
    0.2073
    0.1828
    0.1633

but when I run the code I am promted to say that my matrix inner dimensions must agree to solve this equation. Can anybody please help me with this?

Thanks, Kevin

Anywhere you have a "*" or "/", replace that with ".*" and "./".

I assume you are doing the calculation of F for each pair of X and Phi. Only when you do vector and matrix products use the "*" or "/". Otherwise always ".*" and "./".
