how to make a for loop into a table

I am new to mat lab so this might sound like a dumb question but how do i make a for loop into a table this is how the teacher said to do it but it does not work the way she wants it

%%Part1

for ounces=1:16;

      grams(ounces)=(ounces*28.3495) %grams;
  end

T = table(ounces,grams)

You need to give them to table as column vectors:

ounces=1:16;
for oz = 1:length(ounces)
    grams(oz)=(ounces(oz)*28.3495); %grams;
end

T = table(ounces(:),grams(:))

T =

    16×2 table

      Var1     Var2 
      ____    ______

       1      28.349
       2      56.699
       3      85.048
       4       113.4
       5      141.75
       6       170.1
       7      198.45
       8       226.8
       9      255.15
      10       283.5
      11      311.84
      12      340.19
      13      368.54
      14      396.89
      15      425.24
      16      453.59

I also created a separate array for ‘ounces’ because you need to use it later, and created an index into it. This approach will prevent indexing error problems if ‘ounces’ had fractional elements.

how do i change the Var1 to ounces and the Var2 to grams in the table also ty very much for the help

[Star Strider]

My pleasure.

Use the 'VariableNames' name-value pair:

T = table(ounces(:),grams(:), 'VariableNames',{'Ounces','Grams'})

With that change, ‘T’ now becomes:

T =

    16×2 table

      Ounces    Grams 
      ______    ______

       1        28.349
       2        56.699
       3        85.048
       4         113.4
       5        141.75
       6         170.1
       7        198.45
       8         226.8
       9        255.15
      10         283.5
      11        311.84
      12        340.19
      13        368.54
      14        396.89
      15        425.24
      16        453.59

If you preallocate ounces and grams as columns, and call table as

T = table(ounces,grams)

you don't even have to set the var names. table picks them up automatically.
