hi, i am having c code how to write the below code in matlab
for (i = 0 ; i < n; i++)
scanf("%d", &num[i]);
for (j = 1; j <= n; j++) {
for (i = 0; i < n-1; i++) {
temp = num[i];
num[i] = num[i+1];
num[i+1] = temp;
print(num, n);
}
}

%Please note I did not check the logic of the code
for i=1:n
check here sscanf
for j=1:n
for i=1:n
temp=num(i);
num(i)=num(i+1);
num(i+1)=temp;
fprintf('%d %d',num,n)
end
end
end

@KALYAN ACHARJYA it is for finding permutation of n numbers

Ran in:
For the most part, it is not possible to create a variable in MATLAB that is restricted to a certain range -- not without creating your own object oriented class and being willing to use strict rules about how to assign values to the variables.
You can create symbolic variables and give the symbolic engine assumptions about the range, in a way that in some cases the symbolic engine can reason about the value
syms x
Pi = sym(pi);
assume(x > -Pi & x < Pi)
assumptions
ans = 
isAlways( imag(sin(x)) == 0)
ans = logical
1
In some cases you can configure optimization variables to be in a particular range; see https://www.mathworks.com/help/optim/ug/optimconstr.html

The sin(pi/4) part can be written as
sin(pi/4)
The e^ part should be written as exp
exp(-3/2)
Note however, that instead of sin(pi/4) you get better precision if you write
sinpi(1/4)
