Trouble with getting table=() to work

Question

0 voti

Hello, I just started playing around with some basic text formatting with Matlab. In one set of code I had zero problems getting the table function to work as expected, yet now using the same basic format it is providing a worthless error:

Error: File: my.m Line: 97 Column: 44 The expression to the left of the equals sign is not a valid target for an assignment.

the following lines provide nice clean column matrices as is required for my table output. they are all 6x1:

Element = {'Theta';'R';'Xm';'Z';'Req';'Xeq'}
Open_Circuit = {thetaSC;Rc;Xm;'NA';'NA';'NA'}
Short_Circuit = {'NA';'NA';'NA';Zsc;XZsc;YZsc}
Low_Voltage = {'NA';RCsec;XMsec;'NA';Req_sec;Xeq_sec}

When I run them without the ; they produce the following:

Element =

    'Theta'
    'R'
    'Xm'
    'Z'
    'Req'
    'Xeq'

Open_Circuit =

    [    1.3134]
    [1.7633e+03]
    [  534.0370]
    'NA'        
    'NA'        
    'NA'

Short_Circuit =

    'NA'              
    'NA'              
    'NA'              
    [0.5589 + 2.1231i]
    [          0.5589]
    [          2.1231]

Low_Voltage =

    'NA'      
    [440.8333]
    [133.5093]
    'NA'      
    [  0.1397]
    [  0.5308]

This is correct behavior for those lines of code, yet when I add the following everything blows up:

Equivalen_Circuit_through_Low-voltage_Side = table(Open_Circuit,Short_Circuit,Low_Voltage,'RowNames',Element)

Matlab provides a worthless error message from above. I see no difference between this broken code and the following fully functional code:

Element = {'R primary';'X primary';'Rc';'Xm';'R secondary';'X secondary'};
per = {'pu';'pu';'pu';'pu';'pu';'pu'};
Value = {Rp_pu;Xp_pu;Rc_pu;Xm_pu;Rs_pu;Xs_pu};
Per_Unit_Values = table(per,Value,'RowNames',Element);

This produces a nice clean table as expected:

Per_Unit_Values =

                   per       Value  
                   ____    _________
    R primary      'pu'    [ 0.0100]
    X primary      'pu'    [ 0.0141]
    Rc             'pu'    [78.1250]
    Xm             'pu'    [ 9.3750]
    R secondary    'pu'    [ 0.0043]
    X secondary    'pu'    [ 0.0052]

So I am here asking for some assistance. The table is not required, but its so much nicer then single line responses or worse just allowing the variable to display its answer two lines lower on the screen. Very sloppy output I'd like to avoid.

Thanks in advance.
