matlab如何讀入混合變數格式的dat文件？

現有一個DAT文件，DAT中的變數格式為：

unsigned short usDayCount;

unsigned int uiMsCount;

unsigned int uiMsAttCount;

short sAttRoll;

short sAttPitch;

short sAttYaw;

unsigned int uiMsGpsCount;

int X;

int Y;

int Z;

變數是按聲明順序寫入的。

請問：如何用matlab正確讀入DAT文件中的數據。

謝謝 @Falccm 的耐心指導。代碼寫完回來自己答一下這個問題，為以後有類似問題的知友提供參考。

這個dat文件如falccm所說fread和 memmapfile都是可以讀取的。但由於我的處理系統和這個dat文件的生成系統的高低位不同，所以一開始怎麼讀取都不正確，之後注意下高低位問題就好了。這裡給一下正常情況讀取的代碼示例：

第一種：fread

fid = fopen("A.DAT","rb");

for i=1:1000

[b1(i),c1] = fread(fid,1,"uint16");

[b2(i),c2] = fread(fid,1,"uint32");

[b3(i),c3] = fread(fid,1,"uint32");

[b4(i),c4] = fread(fid,1,"int16");

[b5(i),c5] = fread(fid,1,"int16");

[b6(i),c6] = fread(fid,1,"int16");

[b7(i),c7] = fread(fid,1,"uint32");

[b8(i),c8] = fread(fid,1,"int32");

[b9(i),c9] = fread(fid,1,"int32");

[b10(i),c10] = fread(fid,1,"int32");

end

j=[b1;b2;b3;b4;b5;b6;b7;b8;b9;b10]";

fclose(fid);

第二種：memmapfile

m = memmapfile("A.DAT",...

"Format",{"uint16",[1,1],"Q;...

"uint32",[1,1],"A";...

"uint32",[1,1],"S";...

"int16",[1,1],"D";...

"int16",[1,1],"F";...

"int16",[1,1],"G";...

"uint32",[1,1],"H";...

"int32",[1,1],"X";...

"int32",[1,1],"Y";...

"int32",[1,1],"Z"},"Repeat",inf)

A=m.data;

以上。

fread 可以，不過最合適的應該是建立文件的內存映射：

Create memory map to a file

Map File to Memory
