counting no .of temperature less than 32 in array

function numfreeze = freezing(v)
count = 0;
i =v()
j = 32
if i < 32
    count = count+1
    numfreeze =  count
else
end

geeting errror

i =

45 21 32 31 51 12

j =

32

Output argument "numfreeze" (and maybe others) not assigned during call to "freezing".

Answer 1

[Ngei Katumo]

function w = freezing (A)

w = sum (logical (A(A<32)));

end

Answer 2

[madhan ravi]

v=[45    21    32    31    51    12];
threshold=32;
numfreeze = freezing(v,threshold) % function call

function numfreeze = freezing(v,threshold) % function definition
numfreeze = nnz(v<threshold);
end

[Abhishek singh]

Write a function called freezing that takes a vector of numbers that correspond to daily low temperatures in Fahrenheit. Return numfreeze, the number of days with sub freezing temperatures (that is, lower than 32 F) without using loops

[madhan ravi]

You are pasting the text which you had been asked, if you have any doubts ask.See the answer I gave. Alternatively you can use anonymous function:

v=[45    21    32    31    51    12];
threshold=32;
freeze = @(v,threshold) nnz(v<threshold);
Numfreeze = freeze(v,threshold)

getting error

[madhan ravi]

edit: After the comment from sir Image Analyst

You should save the function in a separate file named freezing.m. "Getting error" is useless, paste the full error message that you’re getting (everything in red).

[Image Analyst]

You mean freezing.m, since that's what was asked.

[madhan ravi]

Ah yes exactly:)

Answer 3

[Nazneen Sayyad]

Write a function called freezing that takes a vector of numbers that correspond to daily low temperatures in Fahrenheit. Return numfreeze, the number of days with sub freezing temperatures (that is, lower than 32 F) without using loops. Here is an example run:

numfreeze = freezing([45 21 32 31 51 12])

numfreeze =

3

function numfreeze = freezing(A)
B=A(A<32);
numfreeze=numel(B);

end

Answer 4

[Ajith Thomas]

function numfreeze=freezing(w)
lowerthan_32=w(w<32);
no_logical_values=lowerthan_32(lowerthan_32>=0);
numfreeze=length(no_logical_values);
end

[Ajith Thomas]

function numfreeze=freezing(w)
lowerthan_32=w(w<32);
numfreeze=numel(lowerthan_32);
end

Answer 5

[Roshan Singh]

function numfreeze = freezing(x)
f = x(x<32);
numfreeze = length(f);
end

Answer 6

[MADHURJYA DAS]

function numfreeze=freezing(A)
x=(A<32);
numfreeze=sum(x(:));
end
