基本语法

pwd()  #查看当前路径
homedir() #查看home工作路径
cd("C:\\Users\\Jonhson\\Documents\\Julia files\\OB")
cd("D:\\LearnFiles\\Research paper\\idea\\MixImpute\\Rcode")
# 存为matlab或读取matlab文件

第一步：安装支持读取.mat文件的MAT包；

Pkg.add("MAT")

第二步：使用安装好的MAT模块；

using MAT

input = matread("mydata.mat");
Xmis = input["Xmis"];
n = size(Xmis)[1];p = size(Xmis)[2]
manual_type_matrix = Array{Symbol}(undef, 100, 100);
manual_type_matrix[:, 1:100] .= :Gaussian;
user_input_estimators = Dict(:NegativeBinomial=> Dict(:r=>6, :p=>0.8))
A = Array{Union{Float64, Missing}}(Xmis);
for i= 1:n
  for j = 1:p
    if(isnan(Xmis[i,j]))
       A[i,j] = missing;
end
end
end
completed_matrix, type_tracker, tracker = complete(A                     = A,
                                                    maxiter               = 200,
                                                    ρ                     = 0.3,
                                                    use_autodiff          = false,
                                                    gd_iter               = 3,
                                                    debug_mode            = false,
                                                   # user_input_estimators = user_input_estimators,
                                                    #project_rank          = 3,
                                                    type_assignment       = manual_type_matrix)

hX = predict(MatrixCompletionModel(),
                            completed_matrix = completed_matrix,
                            type_tracker     = type_tracker,
                            estimators       = user_input_estimators);

file = matopen("matfile.mat", "w");
write(file, "hX", hX);
close(file);
