How to prevent unwanted line breaks when using sgtitle function in figure?

Hello Dears,

I created a general title which is supposed to be 1 line for a figure using the sgtitle function.

sgtitle([ 'Pt: ' pt_blk(si) ', Contact: ' num2str(cont2use(ti)) ',  Target: ' hem{ti} ' ' target{ti} ' ' abbrev{ti}])

for some reason, it created multiple unwanted line breaks. Can anyone help please?

pt_blk is a cell array so pt_blk(si) is a cell array.

['Pt: ', {'429-040 vs 041'}, ', Contact:']

ans = 1×3 cell array
    {'Pt: '}    {'429-040 vs 041'}    {', Contact:'}

Alternately, pt_blk might be a string() array.

Matlab sees the line as a string array

Observe:

['ET' "call" 'home']

ans = 1×3 string array
    "ET"    "call"    "home"

When you concatenate a character vector and a string array, the character vectors are converted into string arrays.

You have several choices:

• You can strjoin the string array
• You can use + to join the parts, such as "Pt: " + pt_blk(si) + ", Contact: ' + cont2use(ti) + ", Target: ' + hem(ti) + ' ' + target(ti) + ' ' + abbrev(ti)
• You can use {} indexing , pt_blk{si} instead of pt_blk(si)

It looks to me as if you are likely already using {} indexing as your solution everywhere other than that one place in the code.

Many thanks, Mr. Roberson. The strjoin function works

sgtitle(strjoin([ 'Pt:' pt_blk(si) ', Contact:' num2str(cont2use(ti)) ', Target:' hem{ti} target{ti} '(' abbrev{ti} ')'] ))
