could anyone help me to solve the issue.

I am having two matrices

A =[0.2616    0.2642    0.2658    0.2658    0.2641    0.2606;
    0.2131    0.1954    0.1776    0.1596    0.1408    0.1209;
    0.1023    0.1066    0.1114    0.1162    0.1202    0.1233;
    0.5003    0.4596    0.4150    0.3665    0.3148    0.2612]


B =[     0    2.2721    2.0537         0         0    1.2945;
    2.4707    1.3124    1.3201         0    1.5619         0;
    1.2997         0         0    1.8159    1.3116         0;
         0         0         0    1.3203         0    1.2975]

I want to get a matrix in such a way that all places of 0 in B should be get filled by the values present in A matrix .

The output of the matrix should be

   [0.2616    2.2721    2.0537    0.2658    0.2641    0.2606;
    2.4707    1.3124    1.3201    0.1596    1.5619    0.1209;
    1.2997    0.1066    0.1114    1.8159    1.3116    0.1233;
    0.5003    0.4596    0.4150    1.3203    0.3148    1.2975]

could anyone please help me on this.

idx = B==0;
B(idx) = A(idx)

Could you help me to solve the issue in the command

A(w)=B(w)

with respect to the matrices given below.

A=[ 3.5849    0.8097         0         0    3.2102         0;
         0         0    3.4263    3.3205         0    0.7748;
    0.8060    3.5170         0         0    0.7909         0;
         0         0    0.8086    0.8024         0    3.1069]
w = [0     0     1     1     0     1;
     1     1     0     0     1     0;
     0     0     1     1     0     1;
     1     1     0     0     1     0]
B =[1.6787    1.6868    1.6845    1.6708    1.6460    1.6111;
    0.1607    0.1771    0.1980    0.2219    0.2471    0.2720;
    8.6233    8.4297    8.1731    7.8765    7.5706    7.2873;
    0.5791    0.4073    0.2409    0.0936    0.1000    0.2262]

When i run the command i am getting the following error

Subscript indices must either be real positive integers or logicals.

Error in line

A(w)=B(w)

Could you please help me on this.

[Torsten]

A = ...;
w = ...;
w = logical(w);
B = ...;
A(w) = B(w);

ok.It works.
