MATLAB: The meaning of basic matlab words

DefinitionsMATLAB

there is alot of words I see in the matlab online document but I wonder what is mean

the first word is argument

and the second word is command line

can you help me, please?

an argument is a constant or variable that you provide to a function; e.g.

sin(x) % here x is the argument to the function sin.

The command line is the line in the command window where you type commands. After you type the command, you hit "enter" and then Matlab evaluates the command and displays the answer. Usually the command line has ">>" at the beginning; so if I type "sin(x) followed by <enter> on the command line, Matlab will calculate sin(x) and display the answer.

>> sin(0.1) <enter>

ans =

0.0998

MATLAB: Storing words

Your line

for iword=1:length(wordbank)

should be

for iword=1:total_no_words

as you do not want to be trying to de-pluralize words that were never stored. length(wordbank) is going to be set by you defining it as a cell array with 25000 entries.

As an optimization, you can replace your checkcount lines that currently say

checkcount=sum(is_letter+is_space);
if checkcount~=length(tline)

with

if ~all(is_letter | is_space)

And after that your line

if strcmp(tline,lower(tline))==1 || strcmp(tline,upper(tline))==1

could be optimized to

if strcmp(tline,lower(tline)) || strcmp(tline,upper(tline))

However! This line checks that time is all in upper-case or all in lower-case and will not store any line that is in mixed-case. Your all-upper-case lines will be stored in upper-case. I suspect you do not intend either of these behaviours, and I cannot tell what you are wanting to check with that "if" statement. I suspect you should be using

tline = lower(tline);

and then storing that unconditionally.

MATLAB: Word input codes in matlab

Hi Charlotte,

Here is how you can perform this. Since you need to check if the first letter of the input word is vowel or not, you can use strcmp and strcmpi functions.

As you written the text already, i am just showing the way you can code it as below:

function out = pigLatinTranslation(word)
    
    % Check if the first letter of the word is vowel or not
    if any(strcmpi(word(1),{'a','e','i','o','u'}))
        out = [word 'way']; % Append 'way' to the word
    else
        out = [word(2:end) word(1) 'ay']; % Place the starting letter at the end and append the 'ay'
    end
end

This when tried as:

>> pigLatinTranslation('pple')
ans =
    'plepay'
>> pigLatinTranslation('apple')
ans =
    'appleway'

Hope this helps.

Regards,

Sriram
