Dimension of the workspace array

l have this matlab code :

 N=51;
 f=[linspace(-1,-.18,164),linspace(-0.1,0.3,80),linspace(.38,1,124)];
 d=[zeros(1,164),ones(1,80),zeros(1,124)].*exp(-1i*pi*f*(N-1)/2);

What is the method to find function have 51 x 386 complex double if f is 368 x 1 double and d is 368 x 1 complex double .

[Walter Roberson]

d=[zeros(1,164),ones(1,80),zeros(1,124)].*exp(-1i*pi*f.*((1:N).'-1)/2);
