How can I make the dimensions agree for this function

f = @(x) x - exp(cos(transpose[1:4])*sum(x)); And x=[2.5;2;1.4;.9] is a column vector. when I subtract it says error Matrix dimensions must agree.

Should it be: f = @(x) x - exp(cos(transpose([1:4]))*sum(x))

Answer 1

[Azzi Abdelmalek]

f = @(x) x.' - exp(cos([1:4]*sum(x)))

[Azzi Abdelmalek]

f = @(x) x - exp(cos([1:4]')*sum(x)); 
x=[2.5;2;1.4;.9] 
f(x)

Thanks, it works now!
