can not update value

hi Matlab

i have done many time to used iteration for

i want to update value in nwc and hWW put it value from fm.WellModel

but always got errors message

nw = fm.getNumberOfWells();         %2
nwc=nan(nw,1);                
hWW=nan(nw,1);
for i = 1:nw
    wm = fm.WellModels{i};  %fm.WellModel consist of 2x1 cell array
    W = wm.W;
    wc = W.cells;
    nwc(i)=numel(W(i).cells);
    hWW(i)=W(i).hW;

Index exceeds matrix dimensions.

vaya - which line of code is generating the error? For which value of i?

[vaya putra]

when i = 1 is okay

but i = 2 is

Index exceeds matrix dimensions.

nwc(i)=numel(W(i).cells);

[Shubham Gupta]

May I know what is stored in W ? What is the size of W ?

[vaya putra]

thank all, i already solved..

Please post the answer. It will help others

by modify this script and its work

[nwc,hWW] =deal(nan(nw,1));

for i = 1:nw

wm = fm.WellModels{i};

W = wm.W;

wc = W.cells;

nwc(i)=W.cells;
