Adding data

Hello,

I have data in the following format:

00    08    255    267    298     300    - time[s]

5     4      3      4      3       2      - values

Time is given in seconds. The values in between stay the same, by this I mean that from 0s to 08s the value is 5 and then it changes to 4. I'd like to create a table (time vs. values) where each second has assigned a value. Something like this:

00 01 02 03 04 05 06 07 08 09 .....

5  5  5  5  5  5  5  5  4  4 .....

Any help is appreciated.

Thanks in advance

t = [0, 8, 255, 267, 298, 300];
x = [5, 4, 3, 4, 3, 2];

index        = zeros(1, t(end) + 1);
index(t + 1) = 1;
index        = cumsum(index);
y            = x(index);

great stuff,

thanks very much for that.

One more question if possible...How to print it into a simple table format( 1st row-time, 2nd row values)

[Walter Roberson]

fprintf('%10g ', index);

fprintf('\n');

fprintf('%10g ', y);

fprintf('\n');

thank you for answering...

but it gives me

1 1 1 1 1 1 1 1 2 2....

5 5 5 5 5 5 5 5 4 4....

instead of

0 1 2 3 4 5 6 7 8 9 .....

5 5 5 5 5 5 5 5 4 4 .....

any suggestion?

thanks
