I am importing a text file into matlab, converting the text to a table and importing each row with numbers as a cell array. I would like to convert each line into individual numbers then insert into a struct. Is there a good approach to this? Example below

line 87: '0.200 0.486 0.000 0.486 0.001 0.100 9.670 -40.808 10.017 3.190 7.886'

=> convert each text number (to an actual number)....

x(1,1) = 0.200,

x(1,2) = 0.486, etc... all while importing into a struct

After your loop ends, you can simply assign all the numbers into a column of a struct. It would be much faster than importing in a loop.

I hope this is what you needed. Hope it helped.

% Vector from 1 to 100
x = 1:1:100
x = 1×100
     1     2     3     4     5     6     7     8     9    10    11    12    13    14    15    16    17    18    19    20    21    22    23    24    25    26    27    28    29    30
% Import into struct (as a 1 column)
struct.Nums = x
struct = struct with fields:
    Nums: [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 … ]
