Finding specific phrases within a cell array (1)

Greetings,

I am working with a total of nine(9) text strings within nine(9) cell ( {9x1} )

and I am trying to take specific sentences of the text strings.

For example, one text string says:

 EAST WINDS 15 TO 20 KNOTS. SEAS 4 TO 6 FEET.

I am trying to divide these two sentences in two structured variables under the name Today.

 Today.Winds = EAST WINDS 15 TO 20 KNOTS
 Today.Waves = SEAS 4 TO 6 FEET

The 9 different strings represents the 7 days of the week, plus today and night forecast, resulting in 9 different strings

The other strings outputs would go like this:

 Tonight.Winds = EAST NORTHEAST WINDS 10 TO 14 KNOTS
 Tonight.Waves = SEAS 3 TO 5 FEET

 Monday.Winds = EAST WINDS 14 TO 19 KNOTS
 Monday.Waves = SEAS 4 TO 6 FEET

I was thinking of telling MATLAB to break when he reaches the first dot and imprint the string as Today.wind, then continue till the next dot, break and imprint it as Today.waves.

How can I do this?

Thank you for your time.

Please stop posting multiple questions about one problem. What should happen with the thread http://www.mathworks.com/matlabcentral/answers/43667-finding-specific-phrases-within-a-cell-array now? Such duplicate questions confuse the readers. It is better to add new information by editing the original question and to mark changes by adding the key "[EDITED]".

My apologies. It won't happen again.

See 'strtok' as one possible solutions. For example:

celltxt{1} = 'EAST WINDS 15 TO 20 KNOTS. SEAS 4 TO 6 FEET.';
[tok, rem] = strtok(celltxt{1}, '.');
Tonight.Winds = tok;
Tonight.Waves = rem(3:end-1); % removing first two and last character

C.J.,

Thank you for the idea, but some of the string have irregularities.

For example, one string instead of ending with a dot, ends with the first word of the presedign sentence.

 EAST WINDS 16 TO 21 KNOTS. SEAS 4 TO 6 FEET. SCATTERED

In consequence, MATLAB outputs this string

 'SEAS 4 TO 6 FEET. SCATTERE'

[C.J. Harris]

In this case you would have to pass the string through the strtok function to again separate them at the full stop. There is no harm passing the 'rem' string though the strtok function again. For example:

celltxt{1} = 'EAST WINDS 15 TO 20 KNOTS. SEAS 4 TO 6 FEET. SCATTERED';
[tok, rem] = strtok(celltxt{1}, '.');
Tonight.Winds = tok;
Tonight.Waves = strtok(rem(3:end), '.');

Sorry for asking so much Harris, is just that I'm about to finish a two month's work. I have this last problem. Some strings end in the start of the preceding string.

For instance,

 EAST NORTHEAST WINDS 13 TO 16 KNOTS. SEAS 3 TO 
 5 FEET. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS.

In this case, MATLAB only outputs

    Winds: 'EAST NORTHEAST WINDS 13 TO 16 KNOTS'
    Waves: 'SEAS 3 TO'

What could I do?

Once again Thank you very much for your help and time.

Juan, "flagging" a message is to bring it to the attention of the moderators in order for them to decide whether to delete it (or to edit out rudeness.) Flagged messages are not brought to the attention of someone you are corresponding with. I don't think you meant to ask the moderators whether your comments were acceptable.

[C.J. Harris]

Well Juan, that would all depend on how you are storing the text. Are you using a cell array?

[Juan Rosado]

Indeed Harris I am using cell array and sorry for the flag.
