Merge two arrays w/o for-loop. Speed-up

Hello Community,

I'm looking for a solution to speed up my script. I have two arrays with the same length. Both arrays must be merged.

B1 = [52, 52, 52, 52, …]

B2 = [0.437288188, 0.437288188, 0.437288188, 0.437288188, ...]

Right now I'm connecting both signals with a for loop, because I need to remove the "0." from array B2:

for k = 1:length(B1)

C(k) = str2num([num2str(B1(k)),'.',strrep(num2str(B2(k),'%.20f'),'0.','')])

end

I want that:

C = [52.437288188, 52.437288188, 52.437288188, 52.437288188, … ]

My solution is very slow. Is there a way to do this element by element without a for-loop?

Thanks in advance.

Best regards,

Malte

B1 = [52, 52, 52, 52] 

B1 = 1×4

52 52 52 52

B2 = [0.437288188, 0.437288188, 0.437288188, 0.437288188] 

B2 = 1×4

0.4373 0.4373 0.4373 0.4373

C=B1+B2

C = 1×4

52.4373 52.4373 52.4373 52.4373

In my system with Precision set

B1 = [52, 52, 52, 52] 
B2 = [0.437288188, 0.437288188, 0.437288188, 0.437288188] 
C=B1+B2

#

B1 =
52    52    52    52
B2 =
0.437288188000000   0.437288188000000   0.437288188000000   0.437288188000000
C =
52.437288187999997  52.437288187999997  52.437288187999997  52.437288187999997

If the objective is only to merge two arrays, then the answer will be different.
