模型是结构体类型的线性投影Y = linproj(X, model) 其中W.model为线性投影矩阵， Y = model.W *X + model.b

b为偏差值- Descr iption:

　 Y = linproj(X, model) linearly projects data in X such that

　　 Y = model.W *X+ model.b



　 out_data = linproj(in_data, model) projects in_data.X

　　 out_data.X = model.W *in_data.X+ model.b

　　 out_data.y = in_data.y



　Input:

　 model [struct] linear projection:

　　.W [dim x ncomp] Projection matrix.

　　.b [ncomp x 1] Bias.
