How to sum the intervals in matlab

Hi

I am struggling in writing the codes, that could generate the new value automatically. Grateful for any help

My scenario is as follows:

value     Error     interval       interval no.  new value
1000       0.5        [0,1]             3        1000*(1+(( 0+ 1)/2)/100)=1005
 800      -1.7        [-2,-1]           1         800*(1+((-2+-1)/2)/100)= 788
.....

here the interval no., say we have 4, we have a list of errors that fall within these intervals

1 [-2, -1] 2 [-1, 0] 3 [0,1] 4[1,2]

my codes so far

v = [1000 800 2000 950 1500]
er = [0.5 -1.7 1.85 -0.25 0.8]
inter1 = [0; -2; 1; -1; 0]
inter2 = [1; -1; 2,; 0; 1]
cal = (1+((inter1+inter2)/2)/100)
nv = cal*v

the output is wrong

this method would be tedious for a many values.

Any help in this matter is highly appreciated.

Many thanks

I have no idea what is the purpose and what is the problem, juste point out you might try

nv = cal.*v.'

[dpb]

v=[1000;800]; err=[0.5;-1.7]; intvl=[0 1;-2 -1]; intvN=[3;1];
newv=v.*[1+mean(intvl,2)/100];

Above yields

>> newv
newv =
   1.0e+03 *
    1.0050
    0.7880
>>
