Matlab Question

king_of_inismac

Ok guys,

Im doing some matlab programming and have come across the following problem:

The matlab code is supposed to represent an equation which includes the square root of e, e being the exponential.

So I tried to implement it as follows:

x() = 2 * sqrt(exp) * i * fc * e^(-1 * 2 *(pi * i * fc)^2);

also I've tried

x() = 2 * sqrt( e ) * i * fc * e^(-1 * 2 *(pi * i * fc)^2);

but both give errors...

Has anyone got any ideas,

Thanks,
Martin

'e' in Matlab is represented as 'exp(1)' "e to the power of 1"

Arrays are indexed using parentheses, don't use square brackets, e.g.
'x(i)', 'x(1,i)' or 'x(i,1)' depending on your row/column preferences

Make sure that your initial value of 'i' is 1. 'x(0)' will throw up an error.

Get ahead of the class and write the square root of e as 'exp(0.5)' "e to the power of 0.5". In long form it's 'sqrt(exp(1))'

don't forget to initialise 'fc' and 'i' . The following code snippet should give you an idea....the values of x will be on one row in this example.

x(1,i) = 2 * sqrt(exp(1)) * i * fc * exp(-2*(pi*fc*i)^2);
