Using MultiBody SmiData in User Defined Functions

Hello , im trying to use some workspace variables(got from datafile of multibody) in matlab function, i tried adding workspace as a paramter but it said :

Mixed field types in structure arrays are not supported. Type at 'smiData.RigidTransform(1).ID' differed from type at 'smiData.RigidTransform(3).ID'.

it is an m file so if i tried to load it , load() function wont do , so any ideas how to do that?, i also tried adding the smiData to the matlab workspace but i think the func/matlab workspace is not the same , any ideas how to pull that off?

function y2 = Funcc(DataNum,Rotz1,Rotz2)
%This Function takes stuff in this order 
%1-Vector that have every Frame in order , regualr
%Frame->ReversedFrame->reg->rev
%2-RotSensor of hip around Z
%3-RotSensor Of knee around z

rotz=-Rotz1 ;
rotz2=-Rotz2;
AxisAngle=0;
NormVector=zeros(3,1);
RotZMat = [cos(rotz) -sin(rotz) 0 0;sin(rotz) cos(rotz)  0 0;0 0 1 0;0 0 0 1];
RotZMat2 = [cos(rotz2) -sin(rotz2) 0 0;sin(rotz2) cos(rotz2)  0 0;0 0 1 0;0 0 0 1];
len=length(DataNum);
A1=zeros(4,4,len);
for i=1:len

AxisAngle=smiData.RigidTransform(DataNum(i)).angle;
NormVector=smiData.RigidTransform(DataNum(i)).axis;
TranslationVector=smiData.RigidTransform(DataNum(i)).translation;
c=cos(AxisAngle);
t1=1-c;
s1=sin(AxisAngle);
xi=NormVector(1);
yi=NormVector(2);
zi=NormVector(3);
x=TranslationVector(1);
y=TranslationVector(2);
z=TranslationVector(3);

A1(:,:,i)=[t1*xi*xi+c t1*xi*yi-zi*s1 t1*xi*zi+yi*s1 x; t1*xi*yi+zi*s1 t1*yi*yi+c t1*yi*zi-xi*s1  y; t1*xi*zi-yi*s1 t1*yi*zi+xi*s1 t1*zi*zi+c z;0 0 0 1];

end
y2 = A1(:,:,1)*RotZMat*(A1(:,:,2)^-1)*A1(:,:,3)*RotZMat2*(A1(:,:,4)^-1)*A1(:,:,5)*(A1(:,:,6)^-1);
