MATLAB: Uniform distribution between a and b with intervals of 0,005

steps;uniform discrete;

Hi,

I am having trouble using R = unidrnd(N) to create n random numbers between a and b (imagine a=0 and b=0.2) where the numbers generated are always a multiple of 0,005. For example: 0,005 0,1 0,15 0,0155 …

Thanks a lot,

How about generating uniform integers between 0 and 0.2/0.005 and multiplying the whole lot by 0.005

R = randi([0 0.2/0.005], 1, 1000) * 0.005; %generate 1000 numbers in multiple of 0.005 between 0 and 0.2

See this example. This consider random values for matrices A and B in fun

rng(0);
A = rand(9);
B = rand(9);
fun = @(x) norm(A*reshape(x,9,9) - B);
rng(4)
x0 = rand(1,81);
lb = zeros(1,81);
ub = ones(1,81)*0.999999;
A = [];
b = [];
Aeq = repelem(eye(9),1,9);
beq = ones(9,1);
nonlcon = [];
options = optimoptions(@fmincon,'Algorithm','sqp','MaxFunctionEvaluations',5000);
x = fmincon(fun,x0,A,b,Aeq,beq,lb,ub,nonlcon, options);
x = reshape(x, 9, 9);
