Convert double type string to data type

%These commands generate the random integers described in the problem statement. %Do not overwrite the values of X and Y in your own code. X = randi([1 10]); Y = randi([1 10]); %Enter the commands for your script mfile here. XandY = ([X, Y]) XplusY = ([X + Y])

The question is totally unclear as to what you are trying to do/ask...give example of what you would want a result to be and for what purpose.

Answer 1

[Walter Roberson]

output1 = compose('Hey, X was %g and Y was %g', X, Y);

I came up with this based on your help and the matlab documentation page

formatSpec = 'The value of X is %d, and the value of Y is %d.';
A1 = X
A2 = Y
XandY = sprintf(formatSpec,A1,A2)

but I received feedback saying that "Variable XandY must be of data type string. It is currently of type char. Check where the variable is assigned a value.At least one character in the text string assigned to XandY is incorrect"

[Walter Roberson]

formatSpec = "The value of X is %d, and the value of Y is %d.";  %notice " not '

thank you so much

Answer 2

hi

simply use the string() command like :

>> X = pi

X =

    3.1416

>> str = string(X)

str = 

    "3.1416"

[I W]

thank you that makes a lot of sense. The question asks the following:

Make a string assigned to the variable XandY and it should present the values by filling in the blank " The value of X is _, and the value of Y is _."

Make a string assigned to the variable XplusY and it should present the sum of the two numbers by filling in the blank " The sum of X and Y is _."

I understand how to get the X and Y values but I do not know how to display it how the question is asking

Answer 3

[Mathieu NOE]

so this is simple string concatenation and then disp (for display in command window:

X = pi
Y = 2.234
disp(['The value of X is ' num2str(X) ' and the value of Y is ' num2str(Y) ' bla bla'])

gives

The value of X is 3.1416 and the value of Y is 2.234 bla bla

[I W]

thank you. How would I assign this to a variable name XandY. Also, can the sprintf function be used to do this, if so how?

[Mathieu NOE]

XandY = X +Y;

disp(['The value of X and Y is ' num2str(XandY)])


% you can also use sprintf
% see help sprintf

I have read through the help page for sprintf but still do not understand it.
