I am new to MATLAB programming and am having trouble even asking the right question. I am trying to assign 6 variables the array data from 6 vertical cells (rows), from a field called "analysis.opt_history.error". When I type this:

A = analysis.opt_history.error

I get the array from the first row (this is OK):

A =

1.068 0.749 0.749 0.737 0.737

However, I also want to retrieve the array data that is in Rows 2 through 6 and assign the values of each cell to B, C, D, E, F separately. I cannot figure out how to do this despite much time reading the community. Thanks!

Mark

在 MATLAB Online 中打开

Is this what you mean?

data={1,2,3,4,5,6}'
data = 6×1 cell array
    {[1]}
    {[2]}
    {[3]}
    {[4]}
    {[5]}
    {[6]}
[A,B,C,D,E,F]=deal(data{:})
A = 1
B = 2
C = 3
D = 4
E = 5
F = 6

That works! Thank you so much for your quick help! I'll need to study cell arrays (and what is not a cell array). Many thanks!
