Integrating Matlab project with c# application with visual studio C#.

I have created one module i.e (Vehicle number plate recognition) in MatLab and the other module (vehicle management system) in C#, Now i want to integrate these. Help me kindly

[Guillaume]

What does integrate these actually mean?

What is it that you don't know how to do?

Have you looked at calling matlab from C# and Calling .Net libraries from matlab?

[Rya]

Integrate mean to combine 2 different modules in one project

See https://www.mathworks.com/matlabcentral/answers/216971-mwarray-assembly-failed-to-be-initialized-in-c

[Rya]

any startup??

[Walter Roberson]

Sorry, I know very little about .NET assemblies.

[Rya]

actually i found difficult to update and delete data from cell array thats why i decided to shift to C#, Can u help me that problem

[Walter Roberson]

Please ask a more specific question about cell arrays.

You use cell arrays much the same way you use other arrays. Construct a logical vector indicating for each row whether the row matches the criteria you have in mind. Then you can use that vector to act on corresponding elements. For example,

car_is_blue = ismember(ANPR(:,6), 'blue');
car_is_sedan = ismember(ANRP(:,7), 'sedan');
car_is_blue_sedan = car_is_blue & car_is_sedan;
blue_sedan_entries = ANPR(car_is_blue_sedan, :);

[Rya]

I m able to show data from cell arrays i.e data about vehicles. now i want to add new data in same cell array and also want to delete specfic data from cell array, how to do that please help?

[Walter Roberson]

ANPR(end+1,:} = CellWithNewData;    %to add data

car_is_blue = ismember(ANPR(:,6), 'blue');
car_is_sedan = ismember(ANRP(:,7), 'sedan');
car_is_blue_sedan = car_is_blue & car_is_sedan;
blue_sedan_entries = ANPR(car_is_blue_sedan, :);

ANPR(blue_sedan_entries,:) = [];    %to delete specific data

[Rya]

This is difficult to understand for me , because here the data that i want to add in a cell array is gathered from user through input dilog box, when user enters data in input dilog box it should automatically store in cell array

[Walter Roberson]

https://www.mathworks.com/help/matlab/ref/inputdlg.html

prompt = {'Enter license plate', 'Enter owner', 'Enter model', 'Enter color', 'Enter year', 'Enter VID'};
dlg_title = 'Enter registration information';
responses = inputdlg(prompt, dlg_title);

new_ANPR_row = responses(:).';   %turn it into a row vector

ANPR(end+1, :) = new_ANPR_row;    %add the entry to the end

[Rya]

this is an array and i want to store every new input in this .

error while using below code

_Subscripted assignment dimension mismatch._

load('DB.mat')
 prompt = {'Enter license plate', 'Enter owner', 'Enter model', 'Enter color', 'Enter year', 'Enter VID'};  
responses = inputdlg(prompt, dlg_title); 
new_ANPR_row = responses(:).';   %turn it into a row vector 
DB(end+1, :) = new_ANPR_row;

[Walter Roberson]

filestruct = load('DB.mat');
DB = filestruct.DB;

prompt = {'Enter license plate', 'Enter owner', 'Enter Vehicle type', 'Enter color', 'Enter manufacturer', 'Enter model', 'Enter year', 'Enter Image file name'};
dlg_title = 'Enter registration information';
responses = inputdlg(prompt, dlg_title);

new_DB_row = responses(:).';   %turn it into a row vector
year_numeric = str2double(new_DB_row{7});
if ~isnan(year_numeric); new_DB_row{7} = year_numeric; end
new_DB_row{8} = uint8(new_DB_row{8}(:));   %I don't know why you do not just leave the file name as a character vector

DB(end+1, :) = new_DB_row;    %add the entry to the end

save DB DB

[Rya]

It works thank you so very much . but when i store data in array, It definetly get stored but when i wish to search or see record/data back in array it requires closing array then opening it again, that does not make a good impression, mean it requires to be refreshed , is there any way to refresh it automatically

[Walter Roberson]

set(handles.DBtable, 'data', DB)      %update your uitable

[Rya]

As i have entered data successfully in cell array but it still gives error while retrieving

Error: Index exceeds matrix dimensions.
  Error in Main>Untitled_1_Callback (line 358)
    Information_About_This_Plate = DB(index_in_database, :);

[Walter Roberson]

You are making me do a lot of guessing about what you might have written in your code.

[Rya]

How should i make you clear?

[Walter Roberson]

... by posting your code? Untitled_1_Callback at the very least, but I suspect I might need more.

[Rya]

The above works well (y) but the last one is to show image in axis?? Its not working, tell me in which format should i save image in array?
