Replace matched values with a cell array keeping unmatched values unchanged

I have a string let's say

A = '[0,     40,    50,    60,    80,    100,   140,   160,   200,   300]';

and another char array, say

B = '48   43   533   6320   840  43  13  13 24  49';

I want to replace numeric values in "A" by numeric values in "B". I tried to match numerical values in B using:

B_num = regexp(A,'\d*','match');

then I tried to replace the numeric values in B without chaging non-numeric values in A using :

A_update = regexprep(A,'\d*',[B_num{:}])

which obivously didn't give the desired results. I know my mistakes but I am unable to really think how I can achieve the desired result.

This code should help

A = '[0,     40,    50,    60,    80,    100,   140,   160,   200,   300]';
B = '48   43   533   6320   840  43  13  13 24  49';

B_num = regexp(B,'\d*','match');
A_pad = regexp(A,'\d*','split');

B_num{end+1}=[];%extend to match size of pad

C=[A_pad(:) B_num(:)]';%put the padding and values back together again
C=C(:)';C(end)=[];%make linear and remove empty last element
C=cell2mat(C);%convert back to char array

But please don't use this in a statement with eval...
