How to print numbers 1 to 4 and add all numbers to a one array?

results

1

2

3

4

a= [1 2 3 4];

[Awais Saeed]

It is a very basic task. Did you try google search?

[Tensi Heshan]

yes I did. Here 1 2 3 4 are taken from loop and all the values (elements) are assigned to a variable "a".

I can don separately but I could not do it together.

Perhaps this is what you want

for col =1:1:4
	disp(col)
	a(col) = col;
end

disp(['a = ',num2str(a)])

[Tensi Heshan]

Thank you.

[Tensi Heshan]

if the number sequance generating from the for loop is complex, then how we do same thing here.

[Awais Saeed]

In the same way

x = rand(1,5) * 10;
y = rand(1,5) * 10;
c = complex(x,y);   % create complex numbers as real(x) + img(y)

for col = 1:1:size(c,2)
    disp(c(col))
    a(col) = c(col);
end

disp(['a = ',num2str(a)])

[Tensi Heshan]

thank you. But it is not working for my code. If you can , could you please correct me.

code is

clc

close all

clear

f=[-6:0.001:6];

n=[-6:6];%range

xt=(-2<=n & n<=2); %X(t) Signal

for t=[-6:0.001:6] %range

fun = @(f)exp(j.*2.*pi.*f.*t);

q = integral(@(f) fun(f),-2,2); %integarte -2 to 2

end;

[Awais Saeed]

Because you are not storing anything. I am assuming you want to store 'q' values

f = -6:0.001:6;
n = -6:6;
xt = (-2<=n & n<=2);
output = [];
for t = -6:0.001:6
    fun = @(f)exp(j.*2.*pi.*f.*t);
    q = integral(@(f) fun(f),-2,2);
    output = [output q];    % store q values
end

[Tensi Heshan]

Right I got the point now, if so i want to assign to a empty array. Thank you for helping me..

Read about fprintf and sum.

Hi, Keep careful, KSSV

add all numbers to a one array

[Tensi Heshan]

No, I want to use for loop and array indexing to the given values of for loop.
