This is amy code it is not working why?

x=[1 4 5 7.5 14 21 23 32]
v=x.^(2) * exp.(x) + x * (( x + log(x)).^(1/2))

Today I formatted your code, next time, use the {}Code button. See here for a GIF showing how to do it.

x=[1 4 5 7.5 14 21 23 32] 

v=x.^(2).*exp(x)+x.*((x+log(x)).^(1/2))

v=vpa(v)

The explanation for answer is this: your code uses matrix multiplications. If you want element-wise operation, you should use the dot-version. This is for * / and ^.

[madhan ravi]

Exactly as Rik Wisselink mentioned element wise operation should be used since your x is a vector

The problem is the dot after exp that shouldn't be there and the missing dots before the two *

%             v----------- problem was here
v=x.^(2) .* exp(x) + x .* (( x + log(x)).^(1/2))
