how to use AND operation

if (eucli<=0.1980) && (eucli>=0.1990) disp('Happy'); end

Operands to the and && operators must be convertible to logical scalar values.

Error in samptest (line 247) if (eucli<=0.1980) && (eucli>=0.1990)

[KSSV]

what is the value of eucli ?

[vasantha malairamar]

we got the eucli as 0.1984 it varies for different images but its value must be between 0.1980 and 0.1990

[KSSV]

eucli = 0.1984 ;
if (eucli<=0.1980) && (eucli>=0.1990)    
    disp('Happy');
else
    disp('unhappy')
end

It is working fine for me without error.

[vasantha malairamar]

we run the same code as you have given but it displays 'unhappy'

[KSSV]

what is your condition actually?

[vasantha malairamar]

we have an array of 7 numbers any one of these 7 values ranges between 0.1980 and 0.1990 then it must display happy or else display sad

(eucli<=0.1980) && (eucli>=0.1990)

?? This is mutually exclusive. No number can be smaller than 0.1980 and greater than 0.1990. Either:

(eucli<=0.1980) || (eucli>=0.1990)

or

(eucli>=0.1980) && (eucli<=0.1990)

Maybe so?

if all(eucli >= 0.1980 & eucli <= 0.1990)
    disp('Happy'); 
else
    disp('Sad');
end

Accept the answer or not?

how can we do this on for loop? like for(i = 0: 20 & j = 0: 10) this is possible or not?
