how to write in matlab

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

looks like circshift isn't it?

[KALYAN ACHARJYA]

@Luna yes. It seems so. Hello @msr16 for circshift, read here and implement, any problem let me know here.

[msr16]

@KALYAN ACHARJYA it is for finding permutation of n numbers

B=3*eye(size)A)-A)

[Walter Roberson]

B = 3 * (eye(size(A)) - A)

create variable for x for (-π,π)

[Walter Roberson]

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

sin(pi/4)+e^-3/2

[Walter Roberson]

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)
