MATLAB: Why this code not displaying else part

if statementrand

the following code is only displaying the if part even if the value is less than 0.6

y = sprintf('%.1f',rand(1))
if y>0.6
    disp('the value is false')
else 
    disp('true') 
 end

Best Answer

Remove sprintf()

MATLAB: Random display of ‘even’ or ‘odd’

Here are the 5 steps you need to take. Since this is your assignment, this answer isn't complete. Each step shows what you need to do in that step but you need to adjust it to your needs. Please feel free to leave a comment if you get stuck.

% Step 1: use rem() to isolate the decimals of a number. 
% In this example, I isolate the decimals of sqrt(2)
d = rem(sqrt(2),1);

% Step 2: extract each number 1-to-n following the decimal point. 
% In this example we extract the decimals of 1/12.
% The result is a char array
n = 8; 
dvec = regexprep(num2str(1/12, sprintf('%%.%df', n)),'^\d+.', '');

% Step 3: isolate the characters of a char array and convert to numeric vector
nv = str2double(num2cell('12345'));

% Step 4: determine of each element of a numeric vector is even/odd
% 'isOdd' will the true for each element that is odd
isOdd = mod([9 8 7 6 5], 2);

% Step 5: convert vector of True/False to 'Odd'/'Even' (where true=Odd)
oddEven = {'Odd','Even'}; 
logicalVector = [true true false true false false false]; 
out = oddEven(~logicalVector+1)

Update: Return a random char array: Even or Odd

after further clarification in the comments below, this is the function you're looking for. The function does not have any inputs. Just call toss() and it will return the character array "EVEN" or "ODD"

function y = toss()
options = {'EVEN','ODD'}; 
y = options{randi([1,2],1)}; 
% If you want to print the output to the command line

fprintf('%s\n',y)

Example

toss()

Alternatively, the first input could be a positive integer that determines the number of random "even" "odd" outputs.

function y = toss(x)
options = {'EVEN','ODD'}; 
y = options(randi([1,2],1,x)); 
% If you want to print the output to the command line
disp(y)

MATLAB: Delete value in matrix with condition

R=arrayfun(@(x)A(x,dist_A(x,:)<0.5),1:size(dist_A,1),'un',0);
R{:}

Gives:

ans =
     1     5
ans =
     1     4     5
ans =
     3     5
