Matlab dimensions must agree error - 


%%pmos cox = 10; co = .25; cjo = .6 ; mj = .3 ; phi_b = 1; cjswo = 0.066; mjsw = 0.1 ; phi_bsw = .5 ; ls = 240000 ; w = 20 ; vd = 0:0.1:1 ;    %%%%% **cj = cjo/((1-(vd/phi_b))).^mj;**           cjsw = cjswo/((1-(vd/phi_bsw))).^mjsw; %%%%%%%%%%%% cdiff_pmos = cj*ls*w + cjsw*(2*ls + w); plot(vd,cdiff_pmos);

the error shows is

error using  /  matrix dimensions must agree.  error in p4_ee115_hw1 (line 14) cj = cjo/((1-(vd/phi_b))).^mj;

any tips on how fix apprecitated. .

if put ./ on line cj , cjsw work. so:

cj = cjo./((1-(vd/phi_b))).^mj; cjsw = cjswo./((1-(vd/phi_bsw))).^mjsw;

you getting error because trying divide scalar vector , matlab picky this. want element wise ./ , remedy code.
