Hi can anyone advise on why lines 21, 22 are not producing an output to the workspace? The table is produced but cannot for somw reason produc Q or T
function [] = TOTAL_HV_CONDUCTOR_DETAILS(cableVoltage,coreType,cableInstallation,cableSize)
%UNTITLED Summary of this function goes here
% Detailed explanation goes here
if strcmp(cableVoltage,'3.8/6.6kV') && strcmp(coreType,'3X1C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3x1C','Range','B11:AU28','VariableNamingRule','preserve','ReadRowNames',true)
elseif strcmp(cableVoltage,'6.35/11kV') && strcmp(coreType,'3X1C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3x1C','Range','B40:AU57','VariableNamingRule','preserve','ReadRowNames',true)
elseif strcmp(cableVoltage,'12.7/22kV') && strcmp(coreType,'3X1C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3x1C','Range','B69:AU84','VariableNamingRule','preserve','ReadRowNames',true)
elseif strcmp(cableVoltage,'19/33kV') && strcmp(coreType,'3X1C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3x1C','Range','B96:AU110','VariableNamingRule','preserve','ReadRowNames',true)
if strcmp(cableVoltage,'3.8/6.6kV') && strcmp(coreType,'3C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3C','Range','B11:AJ24','VariableNamingRule','preserve','ReadRowNames',true)
elseif strcmp(cableVoltage,'6.35/11kV') && strcmp(coreType,'3C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3C','Range','B36:AJ49','VariableNamingRule','preserve','ReadRowNames',true)
elseif strcmp(cableVoltage,'12.7/22kV') && strcmp(coreType,'3C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3x1C','Range','B61:AJ72','VariableNamingRule','preserve','ReadRowNames',true)
elseif strcmp(cableVoltage,'19/33kV') && strcmp(coreType,'3C')
A=readtable('HV_Cable_Parameters.xlsx','Sheet','3C','Range','B84:AJ94','VariableNamingRule','preserve','ReadRowNames',true)
end
Q=summary(A)
T=A(cableSize,cableInstallation)

I would suggest running the code for us here online (not on your computer) so that we can see the result.

By the way, have you consider parameterizing your code?
core_3X1C_params = {
'3.8/6.6Kv', 'B11:AY27'
'6.35/11kV', 'B40:AU57'
'12.7/22kV', 'B69:AU84'
'19/33kV', 'B96:AU110'}
core_3C_params = {
'3.8/6.6Kv', 'B11:AJ24'
'6.35/11kV', 'B40:AJ49'
'12.7/22kV', 'B69:AJ72'
'19/33kV', 'B96:AJ94'}
ismember() against the first column to find the Range information in the second column. The sheet name is the same as the coreType.

You are creating Q and T in the function. Function workspace is different than base workspace. Thats why Q and T is not seen in the base workspace.To do that,
  • You can add Q and T as a output of your function. When you call you need to assign new wariables.
function [Q,T] = TOTAL_HV_CONDUCTOR_DETAILS(cableVoltage,coreType,cableInstallation,cableSize)
  • You can use assignin function in order to save variable to workspace in different scopes.
assignin('base','Q',Q);
assignin('base','T',T);
I prefer to use the first one. The scope of each function should be separated from each other even the base workspace. You can use either.
