Error-Reference to non-existent field

I get an error when executing the code

clc;
clear;
a2=load('DisA.mat')
b2=load('Distance_text1.mat')
c2=load('Distance_c.mat')
d2=load('Distance_Hist.mat')
for i=1:80
    aa=a2.DisA{1,i};%1x96
    bb=b2.Distance_text1{1,i};%1x3
    cc=c2.Distance_c{1,i};%1x4
    dd=d2.Distance_Hist{1,i};%384x1
Features2{i}=[aa,bb,cc,dd'];%1x487
end
save('Features_Distance','Features2')

The error is

Reference to non-existent field 'DisA'.

Error in ==> main at 8
    aa=a2.DisA{1,i};%1x96

the size of each one is

{1x80 cell}

Are you sure you have variable 'DisA' in your file 'DisA.mat'??

[kash]

Yes chandra i have that file

[kash]

my file is

http://www.sendspace.com/file/2uv7w5

[Chandra Kurniawan]

No, not the file. But have you 'VARIABLE' DisA in file DisA.mat??

If it's there,

it's better if you rename your variable 'DisA' with other name.

Or rename your mat-file.

It seem both of your variable and your file have a same name.

[kash]

Iget same error wen i change the name of .mat file

[Chandra Kurniawan]

I'm sorry.

Now, you don't need to rename your file.

Just do what I suggest for you below :)

[Chandra Kurniawan]

No,

I have checked your file 'DisA.mat' and there is no variable named 'DisA'.

It's better if you try to change your code :

aa=a2.DisA{1,i}

with

aa{i} = a2.D{i}

Thanks chandra i got answer ,

this is second part in which i get error

clc;

clear;

a1=load ('SortOut_c2.mat')

b1=load ('SortOut_text1.mat')

c1=load ('SortOut _c.mat')

d1=load ('SortOut_Hist.mat')

for i=1:80

aa=a1.SortOut{1,i};%1x96

bb=b1.SortOut{1,i};%1x3

cc=c1.SortOut{1,i};%1x4

dd=d1.SortOut{1,i};%384x1

Features{i}=[aa,bb,cc,dd'];%1x487

end

save('Features_Sort','Features')

the size is [80x2 double]

the error is

Cell contents reference from a non-cell array object.

Error in ==> main_sor at 8

aa=a1.SortOut{1,i};%1x96

[Chandra Kurniawan]

Are you sure that variable 'SortOut' is a cell??

[kash]

it is not a cell my file is

http://www.sendspace.com/file/efbmab

[Chandra Kurniawan]

Replace

aa=a1.SortOut{1,i};%1x96

with

aa(i) = a1.SortOut(i,1);

[kash]

i get this error

Cell contents reference from a non-cell array object.

Error in ==> main_sor at 8

aa(i)=a1.SortOut{i,1};%1x96

[Chandra Kurniawan]

No, watch carefully.

not {}, but use ()

It must be 'SortOut(i,1);'

Not 'SortOut{i,1};'

[kash]

Thanks chandra ,but i get result as 1x80,but the original size is

2x80,and other is i need those to be placed in column wise

so my final output must be

80 rows and 8 columns

please help

[Chandra Kurniawan]

To get 2x80 just

aa(i,:) = a1.SortOut(i,:);

[kash]

thanks chabdra,finally i get 8 values in a single cell of 80 columns,but i need it to be like this

80 rows and 8 columns

[Chandra Kurniawan]

Now, just type

Features = [aa,bb,cc,dd];

outside the for loop,

and you'll get Features <80x8 doubles> in your workspace

[kash]

thanks Chandra am gretafuk to u,,finaly can u say how to perform

80 rows and 4 column for my first program where size is 1x80

[Chandra Kurniawan]

Do this outside the for-loop

aa = cell2mat(aa');

bb = cell2mat(bb');

cc = cell2mat(cc');

dd = cell2mat(dd');

Features2 = [aa,bb,cc,dd];

[Chandra Kurniawan]

Is your question solved? Was it clear for you?

[kash]

I get an error

Cell contents reference from a non-cell array object.

Error in ==> cell2mat at 38

if isnumeric(c{1}) || ischar(c{1}) || islogical(c{1}) || isstruct(c{1})

Error in ==> main at 17

aa = cell2mat(aa');

[Chandra Kurniawan]

Please show, how do you modify the first code?

[kash]

in my first code i get 4 values in a single cell,so i get 80 columns....

i want is inverse of that 4 column and 80 rows wirh wacs value in each separate cell
