function z= changearray(A)
s = size(A);
nr = s(1);
nc = s(2);
z = zeros(nr,nc);
for i= 1:nr
for j= 1:nc
z(i)(j) = log(A(i)(j));
if (A(i)(j) < 0)
z(i)(j) = A(i)(j)+20;
end
end

4. The goal in this problem is to add two 20 digit integers Sounds easy right? Try this: 1 11111111 1111; printf("%30.08 ) The issue is that the computer cannot store a 20 digit integer exactly. You need to find a ww around this but use non-standard data types (you can't just use a big float) Create a function whose input is two 20 digit integers. Return the sum of the integers. In...

A=[-6,8,2;1,-3,20;15,-10,5]; Write a program that computes the array B by computing the natural logarithm of all the elements of A whose value is greater than or equal to 1. Otherwise add 30 to each element that is less than 1. Do this in two way. A) By using a for loop with conditional statements B)By using a logical array as a mask MATLAB CODE

Matlab code
4) Write a function leadzero(v) which takes as input a vector v and as output, c, returns the number of zeros at the beginning of v (number of zero elements before any non-zero element). For example, for input (-5, 5, 11] the output would be 0. If the input is [0, 0, 3, 0, 0, 0], the output would be 2. If the input is [0, 0, 0, 0, 7, 4) the output would be 4. 5) Write...

What would the function look like in MATLAB? Write a function called mysort that takes a 3-element vector as its sole arguments. It uses if statements, possibly nested, to return a 3-element vector with its elements in non-decreasing order, i.e., the first element in the returned vector equals the smallest element of the input vector and the last element equals the largest element in the input vector. NOTE: Your function should not use any built-in functions, e.g., sort, min, max,...
