显示 更早的评论
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.

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

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.
