How can i generate random variable for j elemnts in my matrix from set of data i've?
i'm trying to write a code for to generate random cases for doing simple data research , i'll be grateful if someone helps me with it , this is my code:
patient_condition=[0.05; 0.15; 0.25; 0.35; 0.45; 0.55; 0.65; 0.75; 0.85; 0.95];
test_type=[0.1 0.26 0.42 0.58 0.74 0.9];
patient_origin=[0.12 0.23 0.34 0.45 0.56 0.67 0.78 0.89];
doctor_orogin=[0.02 0.212 0.404 0.596 0.788 0.98];
patient_age=[0.15 0.4 0.65 0.9];
insurance=[0.04 0.26 0.48 0.7 0.92];
hospital=[0.06 0.24 0.42 0.6 0.77 0.96];
for j=1:1000
p(1,j)=patient_condition(randi(patient_condition));
p(2,j)=test_type(randi(test_type));
p(3,j)=patient_origin(randi(patient_origin));
p(4,j)=doctor_orogin(randi(doctor_orogin));
p(5,j)=patient_age(randi(patient_age));
p(6,j)=insurance(randi(insurance));
p(7,j)=hospital(randi(hospital));
end

I think you mean
patient_condition=[0.05; 0.15; 0.25; 0.35; 0.45; 0.55; 0.65; 0.75; 0.85; 0.95];
test_type=[0.1 0.26 0.42 0.58 0.74 0.9];
patient_origin=[0.12 0.23 0.34 0.45 0.56 0.67 0.78 0.89];
doctor_orogin=[0.02 0.212 0.404 0.596 0.788 0.98];
patient_age=[0.15 0.4 0.65 0.9];
insurance=[0.04 0.26 0.48 0.7 0.92];
hospital=[0.06 0.24 0.42 0.6 0.77 0.96];
p=cell(7,1000);
for j=1:1000
p{1,j}=patient_condition(randi([1 numel(patient_condition)],1));
p{2,j}=test_type(randi([1 numel(test_type)],1));
p{3,j}=patient_origin(randi([1 numel(patient_origin)],1));
p{4,j}=doctor_orogin(randi([1 numel(doctor_orogin)],1));
p{5,j}=patient_age(randi([1 numel(patient_age)],1));
p{6,j}=insurance(randi([1 numel(insurance)],1));
p{7,j}=hospital(randi([1 numel(hospital)],1));
end
