Meaning code setDatType RefMdl

Hello everyone, could someone explain to me what this function mean ? Thank you in advance

function setDataType(ConstantHdl)

BlockName=get_param(ConstantHdl,'Name');
is_ev=~isempty(regexp(BlockName,'^EV_\w*','once'));

if is_ev
    if strcmp(get_param(ConstantHdl,'BlockType'),'Constant')
        set_param(ConstantHdl,'OutDataTypeStr','Inherit: Inherit via back propagation');
    else
        set_param(ConstantHdl,'OutDataTypeStr','Inherit: auto');
    end
else
    is_prm=~isempty(regexp(BlockName,'^\w*_prm_\w*','once'));
    if is_prm
        prefix_regexp='^\w*_prm';
    else
        prefix_regexp='^\w*';
    end
    
    is_bool=~isempty(regexp(BlockName,sprintf('%s_(%s)[A-Z]\\w*',prefix_regexp,'b'),'once'));
    is_int=~isempty(regexp(BlockName,sprintf('%s_(%s)[A-Z]\\w*',prefix_regexp,'ct|idx|no|st'),'once'));
    is_int8=~isempty(regexp(BlockName,sprintf('%s_(%s)[A-Z]\\w*',prefix_regexp,'bf'),'once'));
    if is_int
        set_param(ConstantHdl,'OutDataTypeStr','int32');
    elseif is_bool
        set_param(ConstantHdl,'OutDataTypeStr','boolean');
    elseif is_int8
        set_param(ConstantHdl,'OutDataTypeStr','int8');
    elseif ~isempty(regexp(BlockName,'\w*_[A-Za-z]\w*','once'))
        set_param(ConstantHdl,'OutDataTypeStr','single');
    else
        if strcmp(get_param(ConstantHdl,'BlockType'),'Constant')
            set_param(ConstantHdl,'OutDataTypeStr','Inherit: Inherit via back propagation');
        else
            set_param(ConstantHdl,'OutDataTypeStr','Inherit: auto');
        end
    end
end
set_param(ConstantHdl,'AttributesFormatString','type=%<OutDataTypeStr>');

It is rude to delete all of your comments in a thread; doing that removes all of the context for what the volunteers contributed.

This code is looking for specific block name patterns and based on block name assigning output types for the blocks.

I want tu use this function to change the DataType of the Data Type Conversion

Okay, go ahead and edit the code until it does what you want.

The code looks for particular patterns in the block name, and sets the output data type according to the pattern that was found. If you want the same patterns to be used but want to use a different datatype, then edit the set_param(ConstantHdl,'OutDataTypeStr' statements to use the datatype you want instead. If you want different patterns to be used then edit the lines such as

    is_int=~isempty(regexp(BlockName,sprintf('%s_(%s)[A-Z]\\w*',prefix_regexp,'ct|idx|no|st'),'once'));

to specify the patterns that you want instead of the current patterns.

[Walter Roberson]

Are you asking us to look through the list of blocks on the right hand side of that image, and figure out what the patterns are in the block names that match the datatypes given in the middle, and tell you what new regexp patterns you should use?

[Walter Roberson]

    is_int=~isempty(regexp(BlockName,sprintf('%s_(%s)[A-Z]\\w*',prefix_regexp,'ct|idx|no|st'),'once'));

Currently, the |st part says that if the block name matches _st then this block is an example of an integer block.

If you want to change that so that st blocks are single instead of integer, then remove the |st part of the expression, making it

        is_int=~isempty(regexp(BlockName,sprintf('%s_(%s)[A-Z]\\w*',prefix_regexp,'ct|idx|no'),'once'));
