Need to Produce a different matrix after each loop

Hello Friends,

I need to produce a different set of deli after each loop but it remains the same. Help me out please...see code below.

deli is suppose to be different set of 12 by 1 after each loop

L1=[1 33 34 2 35 36	3 37 38	4 39 40];
L2=[3	37	38	4	39	40	5	41	42	6	43	44];
L3=[5	41	42	6	43	44	7	45	46	8	47	48];
L4=[7	45	46	8	47	48	9	49	50	10	51	52];
L5=[9	49	50	10	51	52	11	53	54	12	55	56];
L6=[11	53	54	12	55	56	13	57	58	14	59	60];
L7=[13	57	58	14	59	60	15	61	62	16	63	64];
L8=[15	61	62	16	63	64	17	65	66	18	67	68];
L9=[17	65	66	18	67	68	19	69	70	20	71	72];
L10=[19	69	70	20	71	72	21	22	23	24	25	26];
L11=[21	22	23	24	25	26	27	28	29	30	31	32];
L=[L1;L2;L3;L4;L5;L6;L7;L8;L9;L10;L11];
delu=[-107.9277784;-473.7489066;-456.4464814;-298.1506906;-38.38102414;169.6616599;218.8447121;105.0260144;-78.47051372;-205.707;-1.1961463;701.7499816;-2084.55571;-1229.851404;-0.390010302;39.67805573;-68.88297022;2231.216584;-5473.430599;-3189.887351;-0.390010302;41.85037402;-72.64553587];
delr=zeros(49,1);
del=[delu;delr];
deli=zeros(12,1);
delbar=([]);
mbar=repmat({zeros(12,1)},n,1);
for i=1:n
    for p=1:12
        deli(p,1)=del((L(i,p)),1);
    end

    mbar{i}=(kg{i}*deli)+fembar{i};
end

It would help if you provide code that can be executed. As posted, the code accesses a few uninitialized variables.

It looks to me as if deli is indeed different after each for i loop. You do not ask to record the value for each i value though.

L1=[1 33 34 2 35 36	3 37 38	4 39 40];
L2=[3	37	38	4	39	40	5	41	42	6	43	44];
L3=[5	41	42	6	43	44	7	45	46	8	47	48];
L4=[7	45	46	8	47	48	9	49	50	10	51	52];
L5=[9	49	50	10	51	52	11	53	54	12	55	56];
L6=[11	53	54	12	55	56	13	57	58	14	59	60];
L7=[13	57	58	14	59	60	15	61	62	16	63	64];
L8=[15	61	62	16	63	64	17	65	66	18	67	68];
L9=[17	65	66	18	67	68	19	69	70	20	71	72];
L10=[19	69	70	20	71	72	21	22	23	24	25	26];
L11=[21	22	23	24	25	26	27	28	29	30	31	32];
L=[L1;L2;L3;L4;L5;L6;L7;L8;L9;L10;L11];
delu=[-107.9277784;-473.7489066;-456.4464814;-298.1506906;-38.38102414;169.6616599;218.8447121;105.0260144;-78.47051372;-205.707;-1.1961463;701.7499816;-2084.55571;-1229.851404;-0.390010302;39.67805573;-68.88297022;2231.216584;-5473.430599;-3189.887351;-0.390010302;41.85037402;-72.64553587];
delr=zeros(49,1);
del=[delu;delr];
deli=zeros(12,1);
delbar=([]);

n = 2; kg = {3;5}; fembar = {2; 103};
mbar=repmat({zeros(12,1)},n,1);
for i=1:n
    for p=1:12
        deli(p,1)=del((L(i,p)),1);
    end
    deli
    mbar{i}=(kg{i}*deli)+fembar{i};
end

deli = 12×1

-107.9278 0 0 -473.7489 0 0 -456.4465 0 0 -298.1507

deli = 12×1

-456.4465 0 0 -298.1507 0 0 -38.3810 0 0 169.6617

Thank you so much.

It is my understanding that you want to produce and store the set of deli after each iteration. In your current code the deli produced after each set is correct you just need to store it as well after each iteration. In the code below each column of delstore represents the set of deli after the corresponding iteration.

L1=[1 33 34 2 35 36	3 37 38	4 39 40];
L2=[3	37	38	4	39	40	5	41	42	6	43	44];
