If i run the following code:

a=0.01
b=0.09
r = 2; c = 10;
[x,v] = randfixedsum(r*c,a,b,0.35);
-------------calling function----------
function [x,v] = randfixedsum(r*c,a,b,0.35)
y = reshape(x,r,c)
v=sum(y(:))
end

I am getting Error in [x,v] = randfixedsum(r*c,a,b,0.35);

Could anyone help me to solve it.

Prabha Kumaresan Yoiu have asked 173 questions so far....and still you have not learned any basics of MATLAB. I feel sorry to say this. You are not at all reading documentation and asking questions in the blog, some one gives some code...you come with slight meaning less changes and even without trying/ reading, you post the same error. This is ridiculous. YOu see the code, you have given:

1. A number cannot be input inside function. You are inputting a number 0.35 inside the function.

2. YOu are trying to reshape x inside the function, this variable is not at all defined to the function.

How you expect us, to solve your problem with lots of typo errors? For the first time we can...but not for the 173rd time. Please be careful while asking questions. And I strongly advice you to read the basics of MATLAB, which are very easy.

在 MATLAB Online 中打开

function myfunction()
r = 2; c = 10;
x = rand(1,2*10) ;
[x,v] = randfixedsum(x,r,c);
end
% -------------calling function----------
function [y,v] = randfixedsum(x,r,c)
y = reshape(x,r,c)
v=sum(y(:))
end

I am surprised...what you are trying to achieve......whether you reshape and do sum on x or directly do sum on x, the answer will be the same.

Actually I want to generate a matrix of random size within the interval [0.01,0.09] such that the sum of the matrix should be 0.35

在 MATLAB Online 中打开

function x = myfunction()
  r = 2; c = 10;
  x = my_randfixedsum(r,c);
end
function y = my_randfixedsum(r,c)
  a = 0.01;
  b = 0.09;
  s = 0.35;
  n = r * c;
  m = 1;
  if n * a > s || n * b < s
     error('Cannot create a sum of %f by adding together %d x %d numbers in the range %f to %f', s, r, c, a, b);
  end
  randomvec = randfixedsum(n, m, s, a, b);
  y = reshape(randomvec, r, c);
end

... just as I told you to do before.

when i run the above code i am getting Error: File: one.m Line: 3 Column: 1 Function definitions are not permitted in this context.

Use the files I have attached. Do not insert any code at the top of either of them. You can have your one.m call myfunction() but do not store these functions in one.m .
